And again it is written, thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths; But verily, verily, I say unto you, swear not at all; neither by heaven, for it is God’s throne; Nor by the earth, for it is his footstool; neither shalt thou swear by thy head, because thou canst not make one hair black or white; But let your communication be Yea, yea; Nay, nay; for whatsoever cometh of more than these is evil.
