Malachi 2:12, 15

As for the man who does this, whoever he may be, may the LORD remove him from the tents of Jacob—even though he brings an offering to the LORD Almighty.

Has not the one God made you? You belong to him in body and spirit. And what does the one God seek? Godly offspring. So be on your guard, and do not be unfaithful to the wife of your youth.
