33 Again, ye have heard that it was said to 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 the 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 shalt thou swear by thy head, for thou canst not make one hair white or black. 37 But let your speech be, Yea, yea; Nay, nay: and whatsoever is more than these is of the evil [one].
