“Again, you have heard that it was said to them of old time, You shall not forswear thyself, but shall perform unto the Lord yours oaths: but I say unto you, swear not at all; neither by the 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 canst not make one hair white or black. But let your speech be, Yea, yea; Nay, nay: and whatsoever is more than these is of the evil one.”
