Malachi 2:14-16

You ask, “Why are our gifts not accepted?” It is because the LORD saw the evil things you did—he is a witness against you. He saw you cheat on your wife. You have been married to her since you were young. She was your girlfriend. Then you made your vows to each other—and she became your wife. God wants husbands and wives to become one body and one spirit. Why? So that they would have holy children and protect that spiritual unity. Don’t cheat on your wife. She has been your wife from the time you were young. The LORD, the God of Israel, says, “I hate divorce, and I hate the cruel things that men do. So protect your spiritual unity. Don’t cheat on your wife.”
