⁷ Thou shalt not take the name of the Lord thy God in vain; for the Lord will not hold him guiltless that taketh his name in vain. — Exodus 20:7

Psalm 15:1-4

Lord, who shall abide in thy tabernacle? who shall dwell in thy holy hill?

² He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart.

³ He that backbiteth not with his tongue, nor doeth evil to his neighbour, nor taketh up a reproach against his neighbour.

⁴ In whose eyes a vile person is contemned; but he honoureth them that fear the Lord. He that sweareth to his own hurt, and changeth not.

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.

Matthew 23:16-22

¹⁶ Woe unto you, ye blind guides, which say, Whosoever shall swear by the temple, it is nothing; but whosoever shall swear by the gold of the temple, he is a debtor!

¹⁷ Ye fools and blind: for whether is greater, the gold, or the temple that sanctifieth the gold?

¹⁸ And, Whosoever shall swear by the altar, it is nothing; but whosoever sweareth by the gift that is upon it, he is guilty.

¹⁹ Ye fools and blind: for whether is greater, the gift, or the altar that sanctifieth the gift?

²⁰ Whoso therefore shall swear by the altar, sweareth by it, and by all things thereon.

²¹ And whoso shall swear by the temple, sweareth by it, and by him that dwelleth therein.

²² And he that shall swear by heaven, sweareth by the throne of God, and by him that sitteth thereon.
