Revision of the Law of Oaths. The prohibition 'Swear not at all' is to be taken in its widest sense, and not simply as forbidding the common oaths of conversation. Christ looks forward to a time when truthfulness will be so binding a duty that oaths will no longer be necessary even in courts of justice. This is one of those ideal commands which cannot be fully carried out in the present state of society. Our Lord Himself at His trial allowed Himself to be put on oath (Matthew 26:63). But one day there will come a time when a man's word will be as good as his oath.

Matthew 5:33-37
33 Again, ye have heard that it hath been said by them of old time, 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 God's throne:
35 Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King.
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.
