Malachi 2:14-16

14And you ask, “Why?” Because even though the Lord has been a witness between you and the wife of your youth, you have acted treacherously against her. She was your marriage partner and your wife by covenant.

15Didn’t God make them one and give them a portion of spirit? What is the one seeking? Godly offspring. So watch yourselves carefully, so that no one acts treacherously against the wife of his youth.

16“If he hates and divorces his wife,” says the Lord God of Israel, “he covers his garment with injustice,” says the Lord of Armies. Therefore, watch yourselves carefully, and do not act treacherously.
