“But I say unto you, Swear not at all; neither by heaven; for it is God's throne: Nor by the earth; for it is his footstool: neither by Jerusalem; for it is the city of the great King.

Matthew 23:16–22

“Woe unto you, 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! fools and blind: for whether is greater, the gold, or the temple that sanctifieth the gold? And, Whosoever shall swear by the altar, it is nothing; but whosoever sweareth by the gift that is upon it, he is guilty. fools and blind: for whether greater, the gift, or the altar that sanctifieth the gift? Whoso therefore shall swear by the altar, sweareth by it, and by all things thereon. And whoso shall swear by the temple, sweareth by it, and by him that dwelleth therein. And he that shall swear by heaven, sweareth by the throne of God, and by him that sitteth thereon.”

James 5:12
