2:15 make one. Malachi here refers to the original creation of man and woman, when He made them “one flesh” (Genesis 2:24). Even though God had allowed divorce among His people under certain circumstances (Deuteronomy 24:1-4), the Lord Jesus made it clear that this was only “because of the hardness of your hearts,” but it was not God’s will (Matthew 19:8). In fact, Malachi says the Lord “hateth putting away” of one’s wife (Malachi 2:16). Some of the Jews had been abandoning their own wives and taking foreign wives, thus risking the same lapse into paganism that had happened long ago when Solomon married “strange wives.” By God’s direction, Nehemiah had sharply rebuked this practice, and required them to separate themselves again (Nehemiah 13:23-30).
