Matthew 5:31–33

Divorce

31 “It has been said, ‘Anyone who divorces his wife must give her a certificate of divorce.’a 32 But I tell you that anyone who divorces his wife, except for marital unfaithfulness, causes her to become an adulteress, and anyone who marries the divorced woman commits adultery.

Oaths

33 “Again, you have heard that it was said to the people long ago, ‘Do not break your oath, but keep the oaths you have made to the Lord.’
