Matthew 5:35-37

Wycliffe Bible

³⁵ neither by the earth, for it is the stool of his feet; neither by Jerusalem, for it is the city of a great king [for it is the city of the great king];

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.
