Matthew 5:33-37 - The Sermon On The Mount: Taking Oaths

33 Again, ye have heard, that it was said to the ancients, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths: 34 but I say unto you, swear not at all; neither by heaven, for it is the throne of God; 35 nor by the earth, for it is his footstool; nor by Jerusalem, for it is the city of the great King: neither shalt thou swear by thy head, 36 for thou canst not make one hair of it white or black: 37 but let your conversation be yea, yea; no, no; for whatever is more than these, cometh from the evil one.
