Matthew 5:36-38

Wycliffe Bible

³⁶ neither thou shalt swear by thine head, for thou mayest not make one hair white, or black;

³⁷ but be your word, Yea, yea; Nay, nay [but your word be Yea, yea; Nay, nay]; and that that is more than these, is of evil.

³⁸ Ye have heard that it hath been said, Eye for eye, and tooth for tooth.
