14 Do you know why? Simple. Because God was there as a witness when you spoke your marriage vows to your young bride, and now you've broken those vows, broken the faith-bond with your vowed companion, your covenant wife. 15 God, not you, made marriage. His Spirit inhabits even the smallest details of marriage. And what does he want from marriage? Children of God, that's what. So guard the spirit of marriage within you. Don't cheat on your spouse. 16 "I hate divorce," says the God of Israel. God-of-the-Angel-Armies says, "I hate the violent dismembering of the 'one flesh' of marriage." So watch yourselves. Don't let your guard down. Don't cheat.

Commentary on Malachi 2:10-17
(Read Malachi 2:10-17)
Corrupt practices are the fruit of corrupt principles; and he who is false to his God, will not be true to his fellow mortals. In contempt of the marriage covenant, which God instituted, the Jews put away the wives they had of their own nation, probably to make room for strange wives. They made their lives bitter to them; yet, in the sight of others, they pretend to be tender of them. Consider she is thy wife; thy own; the nearest relation thou hast in the world. The wife is to be looked on, not as a servant, but as a companion to the husband. There is an oath of God between them, which is not to be trifled with. Man and wife should continue to their lives' end, in holy love and peace. Did not God make one, one Eve for one Adam? Yet God could have made another Eve. Wherefore did he make but one woman for one man? It was that the children might be made a seed to serve him. Husbands and wives must live in the fear of God, that their seed may be a godly seed. The God of Israel saith that he hateth putting away. Those who would be kept from sin, must take heed to their spirits, for there all sin begins. Men will find that their wrong conduct in their families springs from selfishness, which disregards the welfare and happiness of others, when opposed to their own passions and fancies. It is wearisome to God to hear people justify themselves in wicked practices. Those who think God can be a friend to sin, affront him, and deceive themselves. The scoffers said, Where is the God of judgement? but the day of the Lord will come.
