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.
15. Maurer and Hengstenberg explain the verse thus: The Jews had defended their conduct by the precedent of Abraham, who had taken Hagar to the injury of Sarah, his lawful wife; to this Malachi says now, "No one (ever) did so in whom there was a residue of intelligence (discriminating between good and evil); and what did the one (Abraham, to whom you appeal for support) do, seeking a godly seed?" His object (namely, not to gratify passion, but to obtain the seed promised by God) makes the case wholly inapplicable to defend your position. Moore (from Fairbairn) better explains, in accordance with Mal 2:10, "Did not He make (us Israelites) one? Yet He had the residue of the Spirit (that is, His isolating us from other nations was not because there was no residue of the Spirit left for the rest of the world). And wherefore (that is, why then did He thus isolate us as) the one (people; the Hebrew is 'the one')? In order that He might seek a godly seed"; that is, that He might have "a seed of God," a nation the repository of the covenant, and the stock of the Messiah, and the witness for the one God amidst the surrounding polytheisms. Marriage with foreign women, and repudiation of the wives wedded in the Jewish covenant, utterly set aside this divine purpose. Calvin thinks "the one" to refer to the conjugal one body formed by the original pair (Ge 2:24). God might have joined many wives as one with the one husband, for He had no lack of spiritual being to impart to others besides Eve; the design of the restriction was to secure a pious offspring: but compare Note, see on Mal 2:10. One object of the marriage relation is to raise a seed for God and for eternity.
