Matthew 5:33

³¹  It hath been said, Whosoever shall put away his wife, let him give her a writing of divorcement:

³²  But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.

³³  Again, ye have heard that it hath been said by them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths:

³⁴  But I say unto you, Swear not at all; neither by heaven; for it is God's throne:

³⁵  Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King.
