Malachi 2:13-16

13You also do this: You cover the altar of the Lord with tears as you weep and groan, because he no longer pays any attention to the offering nor accepts it favorably from you.

14Yet you ask, “Why?” The Lord is testifying against you on behalf of the wife you married when you were young, to whom you have become unfaithful even though she is your companion and wife by law.

15No one who has even a small portion of the Spirit in him does this. What did our ancestor do when seeking a child from God? Be attentive, then, to your own spirit, for one should not be disloyal to the wife he took in his youth.

16“I hate divorce,” says the Lord God of Israel, “and the one who is guilty of violence,” says the Lord who rules over all. “Pay attention to your conscience, and do not be unfaithful.”
