Teaching about Divorce
31 “You have heard the law that says, ‘A man can divorce his wife by merely giving her a written notice of divorce.’[m] 32 But I say that a man who divorces his wife, unless she has been unfaithful, causes her to commit adultery. And anyone who marries a divorced woman also commits adultery.
Teaching about Vows
33 “You have also heard that our ancestors were told, ‘You must not break your vows; you must carry out the vows you make to the Lord.’[n] 34 But I say, do not make any vows! Do not say, ‘By heaven!’ because heaven is God’s throne. 35 And do not say, ‘By the earth!’ because the earth is his footstool. And do not say, ‘By Jerusalem!’ for Jerusalem is the city of the great King. 36 Do not even say, ‘By my head!’ for you can’t turn one hair white or black. 37 Just say a simple, ‘Yes, I will,’ or ‘No, I won’t.’ Anything beyond this is from the evil one.
