Malachi 2:14-15

14You ask, ‘Why is the Lord not happy with our gifts?’ The Lord knows that you men have not done the right thing with your wives. When you married as a young man, you promised to take care of your wife always. But you have sent her away, when the law says that you must stay with her as your wife.

15The Lord has joined you together, as a man with his wife. Your body and your spirit belong to him. Why did God put you together? He wanted you to have children who would belong to him. So think carefully about how you live. Do not leave the wife that you married when you were a young man.
