Matthew 5:31-41

31 "It has also been said, 'Whoever divorces his wife must give her a written notice.'
32 But I can guarantee that any man who divorces his wife for any reason other than unfaithfulness makes her look as though she has committed adultery. Whoever marries a woman divorced in this way makes himself look as though he has committed adultery.
33 "You have heard that it was said to your ancestors, 'Never break your oath, but give to the Lord what you swore in an oath to give him.'
34 But I tell you don't swear an oath at all. Don't swear an oath by heaven, which is God's throne,
35 or by the earth, which is his footstool, or by Jerusalem, which is the city of the great King.
36 And don't swear an oath by your head. After all, you cannot make one hair black or white.
37 Simply say yes or no. Anything more than that comes from the evil one.
38 "You have heard that it was said, 'An eye for an eye and a tooth for a tooth.'
39 But I tell you not to oppose an evil person. If someone slaps you on your right cheek, turn your other cheek to him as well.
40 If someone wants to sue you in order to take your shirt, let him have your coat too.
41 If someone forces you to go one mile, go two miles with him.
