Malachi 2:15-16

15Didn’t the Lord make you one with your wife? In body and spirit you are his. And what does he want? Godly children from your union. So guard your heart; remain loyal to the wife of your youth.

16“For I hate divorce!” says the Lord, the God of Israel. “To divorce your wife is to overwhelm her with cruelty,” says the Lord of Heaven’s Armies. “So guard your heart; do not be unfaithful to your wife.”
