Malachi 2:14-15

You cry out, “Why doesn’t the LORD accept my worship?” I’ll tell you why! Because the LORD witnessed the vows you and your wife made when you were young. But you have been unfaithful to her, though she remained your faithful partner, the wife of your marriage vows. Didn’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.
