Malachi 2
14 Ref But you say, For what reason? Because the Lord has been a witness between you and the wife of your early years, to whom you have been untrue, though she is your friend and the wife to whom you have given your word.
15 Ref ... So give thought to your spirit, and let no one be false to the wife of his early years.
16 Ref For I am against the putting away of a wife, says the Lord, the God of Israel, and against him who is clothed with violent acts, says the Lord of armies: so give thought to your spirit and do not be false in your acts.
