Matthew 5:33

30 If your right hand causes you to stumble, cut it off, and cast it from you: for it is profitable for you that one of your members should perish, and not your whole body be cast into Gehenna.

31 "It was also said, `Whoever shall put away his wife, let him give her a writing of divorce,`

32 but I tell you that whoever who puts away his wife, except for the cause of sexual immorality, makes her an adulteress; and whoever shall marry her when she is put away commits adultery.

33 "Again you have heard that it was said to them of old time, `You shall not make false vows, but shall perform to the Lord your vows,`

34 but I tell you, don`t swear at all: neither by heaven, for it is the throne of God;

35 nor by the earth, for it is the footstool of his feet; nor by Jerusalem, for it is the city of the great King.

36 Neither shall you swear by your head, for you can`t make one hair white or black.
