(2.) The character given of such worshippers. They are deceivers; they deal falsely and fraudulently with God; they play the hypocrite with him; they pretend to honour him, in making the vow, but, when it comes to be performed, they put an affront upon him, to such a degree that it would have been better not to have vowed than to vow and thus to pay; but let not such be themselves deceived, for God is not mocked. Those who think to put a cheat upon God will prove, in the end, to have put a ****ing cheat upon their own souls. Hypocrites are deceivers, and they will prove self-deceivers, and so self-destroyers.
(3.) The doom passed upon them: They are cursed; they expect a blessing, but will meet with a curse, the tokens of God's wrath, according to the judgment written.
(4.) The reason of this doom: "For I am a great King, saith the Lord of hosts, and therefore will reckon with those who deal with me but as a man like themselves; my name is dreadful among the heathen, and therefore I will not bear that it should be contemptible among my own people." The heathen paid more respect to their gods, though idols, than the Jews did to theirs, though the only true and living God. Note, The consideration of God's universal dominion, and the universal acknowledgment of it, should restrain us from all irreverence in his service.

From Matthew Henry's Commentary

Malachi 2 ( Unlawful Marriage )

2:1 And now, O ye priests, this commandment is for you.
2 If ye will not hear, and if ye will not lay it to heart, to give glory unto my name, saith the LORD of hosts, I will even send a curse upon you, and I will curse your blessings: yea, I have cursed them already, because ye do not lay it to heart.
3 Behold, I will corrupt your seed, and spread dung upon your faces, even the dung of your solemn feasts; and one shall take you away with it.
4 And ye shall know that I have sent this commandment unto you, that my covenant might be with Levi, saith the LORD of hosts.
5 My covenant was with him of life and peace; and I gave them to him for the fear wherewith he feared me, and was afraid before my name.
6 The law of truth was in his mouth, and iniquity was not found in his lips: he walked with me in peace and equity, and did turn many away from iniquity.
7 For the priest's lips should keep knowledge, and they should seek the law at his mouth: for he is the messenger of the LORD of hosts.
8 But ye are departed out of the way; ye have caused many to stumble at the law; ye have corrupted the covenant of Levi, saith the LORD of hosts.
9 Therefore have I also made you contemptible and base before all the people, according as ye have not kept my ways, but have been partial in the law.
10 Have we not all one father? hath not one God created us? why do we deal treacherously every man against his brother, by profaning the covenant of our fathers?
11 Judah hath dealt treacherously, and an abomination is committed in Israel and in Jerusalem; for Judah hath profaned the holiness of the LORD which he loved, and hath married the daughter of a strange god.
12 The LORD will cut off the man that doeth this, the master and the scholar, out of the tabernacles of Jacob, and him that offereth an offering unto the LORD of hosts.
13 And this have ye done again, covering the altar of the LORD with tears, with weeping, and with crying out, insomuch that he regardeth not the offering any more, or receiveth it with good will at your hand.
14 Yet ye say, Wherefore? Because the LORD hath been witness between thee and the wife of thy youth, against whom thou hast dealt treacherously: yet is she thy companion, and the wife of thy covenant.
15 And did not he make one? Yet had he the residue of the spirit. And wherefore one? That he might seek a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth.
16 For the LORD, the God of Israel, saith that he hateth putting away: for one covereth violence with his garment, saith the LORD of hosts: therefore take heed to your spirit, that ye deal not treacherously.
17 Ye have wearied the LORD with your words. Yet ye say, Wherein have we wearied him? When ye say, Every one that doeth evil is good in the sight of the LORD, and he delighteth in them; or, Where is the God of judgment?

Malachi 2:10-17

Unlawful marriages

Corrupt practices are the genuine fruit and product of corrupt principles; and the badness of men's hearts and lives is owing to some loose atheistical notions which they have got and which they govern themselves by. Now, in these verses, we have an instance of this; we here find men dealing falsely with one another, and it is because they think falsely of their God. Observe,
I. How corrupt their practices were. In general, they dealt treacherously every man against his brother, v. 10. It cannot be expected that he who is false to his God should be true to his friend. They had dealt treacherously with God in his tithes and offerings, and had defrauded him, and thus conscience was debauched, its bonds and cords were broken, a door was opened to all manner of injustice and dishonesty, and the bonds of relation and natural affection are broken through likewise and no difficulty made of it. Some think that the treacherous dealings here reproved are the same with those instances of oppression and extortion which we find complained of to Nehemiah about this time, Neh 5:3-7. Therein they forgot the God of their fathers, and the covenant of their fathers, and rendered their offerings unacceptable, Isa 1:11. But it seems rather to refer to what was amiss in their marriages, which was likewise complained of, Neh 13:23. Two things they are here charged with, as very provoking to God in this matter-taking strange wives of heathen nations, and abusing and putting away the wives they had of their own nation; in both these they dealt treacherously and violated a sacred covenant; the former was in contempt of the covenant of peculiarity, the latter of the marriage-covenant.
1. In contempt of the covenant God made with Israel, as a peculiar people to himself, they married strange wives, which was expressly prohibited, and provided against, in that covenant, Deut 7:3. Observe here,
(1.) What good reason they had to deal faithfully with God and one another in this covenant, and not to make marriages with the heathen.
[1.] They were expressly bound out from such marriages by covenant. God engaged to do them good upon this condition, that they should not mingle with the heathen; this was the covenant of their fathers, the covenant made with their fathers, denoting the antiquity and the authority of it, and its being the great charter by which that nation was incorporated. They lay under all possible obligations to observe it strictly, yet they profaned it, as if they were not bound by it. Those profane the covenant of their fathers who live in disobedience to the command of the God of their fathers.
[2.] They were a peculiar people, united in one body, and therefore ought to have united for the preserving of the honour of their peculiarity: Have we not all one Father? Yes, we have, for has not one God created us? Are we not all his offspring? And are we not made of one blood? Yes, certainly we are. God is a common Father to all mankind, and, upon that account, all we are brethren, members one of another, and therefore ought to put away lying (Eph 4:25), and not to deal treacherously, no, not any man against his brother. But here it seems to refer to the Jewish nation: Have we not all one father, Abraham, or Jacob? This they prided themselves in, We have Abraham to our father; but here it is turned upon them as an aggravation of their sin in betraying the honour of their nation by intermarrying with heathens: "Has not one God created us, that is, formed us into a people, made us a nation by ourselves, and put a life into us, distinct from that of other nations? And should not this oblige us to maintain the dignity of our character?" Note, The consideration of the unity of the church in Christ, its founder and Father, should engage us carefully to preserve the purity of the church and to guard against all corruptions.
[3.] They were dedicated to God, as well as distinguished from the neighbouring nations. Israel was holiness to the Lord (Jer 2:3), taken into covenant with him, set apart by him for himself, to be to him for a name and a praise, and upon this account he loved them and delighted in them; the sanctuary set up among them was the holiness of the Lord, which he loved, of which he said, It is my rest for ever, here will I dwell, for I have desired it; but by marrying strange wives they profaned this holiness, and laid the honour of it in the dust. Note, Those who are devoted to God, and beloved of him, are concerned to preserve their integrity, that they may not throw themselves out of his love, nor lose the honour, or defeat the end, of their dedication to him.
(2.) How treacherously they dealt, notwithstanding, They profaned themselves in that very thing which was prescribed to them for the preserving of the honour of their singularity: Judah has married the daughter of a strange god. The harm was not so much that she was the daughter of a strange nation (God has made all nations of men, and is himself King of nations), but that she was the daughter of a strange god, trained up in the service and worship of false gods, at their disposal, as a daughter at her father's disposal, and having a dependence upon them; hence some of the rabbin (quoted by Dr. Pocock) say, He that marries a heathen woman is as if he made himself son-in-law to an idol. The corruption of the old world began with the intermarriages of the sons of God with the daughters of men, Gen 6:2. It is the same thing that is here complained of, but as it is expressed it sounds worse: The sons of God married the daughters of a strange god. Herein Judah is said to have dealt treacherously, for they basely betrayed their own honour and profaned that holiness of the Lord which they should have loved (so some read it); and it is said to be an abomination committed in Israel and in Jerusalem; it was hateful to God, and very unbecoming those that were called by his name. Note, it is an abominable thing for those who profess the holiness of the Lord to profane it, particularly by yoking themselves unequally with unbelievers.
(3.) How severely God would reckon with them for it (v. 12): The Lord will cut off the man that doeth this, that marries the daughter of a strange god. He has, in effect, cut himself off from the holy nation, and joined in with foreigners and aliens to the commonwealth of Israel, and so shall his doom be; God will cut him off, him and all that belongs to him; so the original intimates. He shall be cut off from Israel and from Jerusalem, and not be written among the living there. The Lord will cut off both the master and the scholar, that are guilty of this sin, both the teachers and the taught. The blind leaders and the blind followers shall fall together into the ditch, both him that wakeneth and him that answereth (so it is in the margin), for the master calls up his scholar to his business, and stirs him up in it. They shall be cut off together out of the tabernacles of Jacob. God will no more own them as belonging to his nation; nay, and the priest that offers an offering to the Lord, if he marry a strange wife (as we find many of the priests did, Ezra 10:18), shall not escape; the offering he offers shall not atone for him, but he shall be cut off from the temple of the Lord, as others from the tabernacles of Jacob. Nehemiah chased away from him, and from the priesthood, one of the sons of the high priest, whom he found guilty of this sin, Neh 13:28.
2. In contempt of the marriage-covenant, which God instituted for the common benefit of mankind, they abused and put away the wives they had of their own nation, probably to make room for those strange wives, when it was all the fashion to marry such (v. 13): This also have you done; this is the second article of the charge. For the way of sin is down-hill, and one violation of the covenant is an inlet to another.
(1.) Let us see what it is that is here complained of. they did not behave as they ought to have done towards their wives.
[1.] They were cross with them, froward and peevish, and made their lives bitter to them, so that when they came with their wives and families to worship God at the solemn feasts, which they should have done with rejoicing, they were all out of humour; the poor wives were ready to break their hearts, and, not daring to make their case known to any other, they complained to God, and covered the altar of the Lord with tears, with weeping, and with crying. This is illustrated by the instance of Hannah, who, upon the account of her husband's having another wife (though otherwise a kind husband), and the discontent thence arising, whenever they went up to the house of the Lord to worship fretted and wept, and was in bitterness of soul, and would not eat, 1 Sam 1:6-7,10. So it was with these wives here; and this was so contrary to the cheerfulness which God requires in his worshippers that it spoiled the acceptableness of their devotions: God regards not their offering any more. See here what a good Master we serve, who will not have his altar covered with tears, but compassed with songs. This condemns those who left his worship for that of idols, among the rites of which we find women weeping for Tammuz (Ezek 8:14), and the blood of the worshippers gushing out upon the altar, 1 Kings 18:28. See also what a wicked thing it is to put others out of frame for the cheerful worship of God; though it is their fault by their fretfulness to indispose themselves for their duty, yet it is much more the fault of those who provoked them to make them to fret. It is a reason given why yoke-fellows should live in holy love and joy - that their prayers may not be hindered, 1 Peter 3:7.
[2.] They dealt treacherously with them, v. 14-16. They did not perform their promises to them, but defrauded them of their maintenance or dower, or took in concubines, to share in the affection that was due to their wives only.
[3.] They put them away, gave them a bill of divorce, and turned them off, nay, perhaps they did it without the ceremony that the law of Moses prescribed, v. 16.
[4.] In all this they covered violence with their garment; they abused their wives, and were vexatious to them, and yet, in the sight of others, they pretended to be very loving to them and tender of them, and to cast a skirt over them. It is common for those who do violence to advance some specious pretence or other wherewith to cover it as with a garment.
(2.) Let us see the proof and aggravations of the charge.
[1.] It is sufficiently proved by the testimony of God himself: "The Lord has been witness between thee and the wife of thy youth (v. 14), has been witness to the marriage-covenant between thee and her, for to him you appealed concerning your sincerity in it and fidelity to it; he has been a witness to all the violations of it, and all thy treacherous dealings in contempt of it, and is ready to judge between thee and her." Note, This should engage us to be faithful both to God and to all with whom we have to do, that God himself is a witness both to all our covenants and to all our covenant-breaches; and he is a witness against whom there lies no exception.
[2.] It is highly aggravated by the consideration of the person wronged and abused. First, "She is thy wife; thy own, bone of thy bone and flesh of thy flesh, the nearest to thee of all the relations thou hast in the world, and to cleave to whom thou must quit the rest." Secondly, "She is the wife of thy youth, who had thy affections when they were at the strongest, was thy first choice, and with whom thou hast lived long. Let not the darling of thy youth be the scorn and loathing of thy age." Thirdly, "She is thy companion; she has long been an equal sharer with thee in thy cares, and griefs, and joys." The wife is to be looked upon, not as a servant, but as a companion to the husband, with whom he should freely converse and take sweet counsel, as with a friend, and in whose company he should take delight more than in any other's; for is she not appointed to be thy companion? Fourthly, "She is the wife of thy covenant, to whom thou art so firmly bound that, while she continues faithful, thou canst not be loosed from her, for it was a covenant for life. It is the wife with whom thou hast covenanted, and who has covenanted with thee; there is an oath of God between you, which is not to be trifled with, is not to be played fast and loose with." Married people should often call to mind their marriage-vows, and review them with all seriousness, as those that make conscience of performing what they promised.
(3.) Let us see the reasons given why man and wife should continue together, to their lives' end, in holy love and peace, and neither quarrel with each other nor separate from each other.
[1.] Because god has joined them together (v. 15): Did not he make one, one Eve for one Adam, that Adam might never take another to her to vex her (Lev 18:18), nor put her away to make room for another? It is great wickedness to complain of the law of marriage as a confinement, when Adam in innocency, in honour, in Eden, in the garden of pleasure, was confined to one. Yet God had the residue of the Spirit; he could have made another Eve, as amiable as that he did make, but, designing Adam a help meet for him, he made him one wife; had he made him more, he would not have had a meet help. And wherefore did he make but one woman for one man? It was that he might seek a godly seed - a seed of God (so the word is), a seed that should bear the image of God, be employed in the service of God, and be devoted to his glory and honour,-that every man having his own wife, and but one, according to the law, (1 Cor 7:2), they might live in chaste and holy love, under the directions and restraints of the divine law, and not, as brute beasts, under the dominion of lust, and thus might propagate the nature of man in such a way as might make it most likely to participate of a divine nature,-that the children, being born in holy matrimony, which is an ordinance of God, and by which the inclinations of nature are kept under the regulations of God's command, might thus be made a seed to serve him, and be bred, as they are born, under his direction and dominion. Note, The raising up of a godly seed, which shall be accounted to the Lord for a generation, is one great end of the institution of marriage; but that is a good reason why the marriage-bed should be kept undefiled and the marriage bond inviolable. Husbands and wives must therefore live in the fear of God, that their seed may be a godly seed, else were they unclean, but now they are holy, as children of the covenant, the marriage-covenant, which was a type of the covenant of grace, and the conjugal union, when thus preserved entire, of the mystical union between Christ and his church, in which he seeks and secures to himself a godly seed; see Eph 5:25,32.
[2.] Because he is much displeased with those who go about to put asunder what he has joined together (v. 16): The God of Israel saith that he hateth putting away. He hath indeed permitted it to the Jews, for the hardness of their hearts, or, rather, limited and clogged it (Matt 19:8); but he hated it, especially as those practised it who put away their wives for every cause, Matt 19:3. Let those wives that elope from their husbands and put themselves away, those husbands that are cruel to their wives and turn them away, or take their affections off from their wives and place them upon others, yea, and those husbands and wives that live asunder by consent, for want of love to each other, let such as these know that the God of Israel hates such practices, however vain men may make a jest of them.
(4.) Let us see the caution inferred from all this. We have it twice (v. 15): Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth; and again, v. 16. Note, Those that would be kept from sin must take heed to their spirits, for there all sin begins; they must keep their hearts with all diligence, must keep a jealous eye upon them and a strict hand, and must watch against the first risings of sin there. We shall act as we are spirited; and therefore, that we may regulate our actions, we must consider what manner of spirit we are of; we must take heed to our spirits with reference to our particular relations, and see that we stand rightly affected to them and be of a good temper, for otherwise we shall be in danger of dealing treacherously. If our own hearts deal treacherously with us, whom will they not deal treacherously with?
II. Observe how corrupt their principles were, to which were owing all these corrupt practices. Let us trace up the streams to the fountain (v. 17): You have wearied the Lord with your words. They thought to evade the convictions of the word, and to justify themselves by cavilling with God's proceedings; but their defence was their offence, and their vindication of themselves was the aggravation of their crime; they affronted the Lord with their words, and repeated them so often, and persisted so long in their contradictions, that they even wearied him; see Isa 7:13. They made him weary of doing them good as he had done, and stopped the current of his favours; or they represented him as weary of governing the world, and willing to quit it and lay aside the care of it. Note, It is a wearisome thing, even to God himself, to hear people insist upon their own justification in their corrupt and wicked practices, and plead their atheistical principles in vindication of them. But, as if God by his prophet had done them wrong, see how impudently they ask, Wherein have we wearied him? What are those vexatious words whereby we have wearied him? Note, Sinful words are more offensive to the God of heaven than they are commonly thought to be. But God has his proofs ready; two things they had said, at least in their hearts (and thoughts are words to God), with which they had wearied him:-
1. They had denied him to be a holy God, and had asserted that concerning him which is directly contrary to the doctrine of his holiness. As he is a holy God, he hates sin, is of purer eyes than to behold it, and cannot endure to look upon it, Hab 1:13. He is not a God that has pleasure in wickedness, Ps 5:4. And yet they had the impudence to say, in direct contradiction to this, Every one that does evil is good in the sight of the Lord, and he delights in them. This wicked inference they drew, without any reason, from the prosperity of sinners in their sinful courses (see Mal 3:15), as if God's love or hatred were to be known by that which is before us, and those must be concluded good in the sight of the Lord who are rich in the world. Or this they said because they wished it might be so; they were resolved to do evil, and yet to think themselves good in the sight of the Lord, and to believe that he delighted in them, notwithstanding; and therefore, under pretence of making God not so severe as he was commonly represented, they said as they would have it, and thought he was altogether such a one as themselves. Note, Those who think God a friend to sin affront him and deceive themselves.
2. They had denied him to be the righteous governor of the world. If he did not delight in sin and sinners, yet it would serve their turn to believe that he would never punish it or them. They said, "Where is the God of judgment? That God who, we have been so often told, would call us to an account, and reckon with us for what we have said and done-where is he? He has forsaken the earth, and takes no notice of what is said and done there; he has said that he will come to judgment; but where is the promise of his coming? We may do what we please; he sees us not, nor will regard us." It is such a challenge to the Judge of the whole earth as bids defiance to his justice, and, in effect, dares him to do his worst. Such scoffers as these there were in the latter days of the Jewish church, and such there shall be in the latter days of the Christian church; but their unbelief shall not make the promise of God of no effect; for the day of the Lord will come. Behold, the Judge stands before the door; the God of judgment is at hand.
