Matthew 5:33

If your right hand causes you to stumble, cut it off, and throw it away from you. For it is more profitable for you that one of your members should perish, than for your whole body to be cast into Gehenna.

“It was also said, ‘Whoever shall put away his wife, let him give her a writing of divorce,’

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

but I tell you, don’t swear at all: neither by heaven, for it is the throne of God;

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

Neither shall you swear by your head, for you can’t make one hair white or black.
