Now viewing scripture range from the book of Matthew chapter 5:33 through chapter 5:37...
34 But I say unto you, Swear not at all; neither by heaven; for it is God's throne:
36 Neither shalt thou swear by thy head, because thou canst not make one hair white or black.
37 But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.
