Matthew 5:33-37

Thomson(i) 33 Again you have heard that it hath been said to the ancients, Thou shalt not forswear thyself; but shalt perform thine oaths to the Lord. 34 But I say to you, Swear not at all: neither by heaven, for it is God's throne: 35 nor by the earth, for it is his footstool; nor by Jerusalem; for it is the city of the great king, 36 neither shalt thou swear by thy head; for thou canst not make one hair white or black. 37 But let your word yes, be yes; and your no, no; for whatever exceedeth these, proceedeth from that which is evil.
