Matthew 5:36-40

Neither shalt thou swear by thy head, because thou canst not make one hair white or black.

But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.

Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth:

But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.

And if any man will sue thee at the law, and take away thy coat, let him have thy cloke also.
