Law of solemn pledges

³³ “Again you have heard that it was said to those who lived long ago: Don’t make a false solemn pledge, but you should follow through on what you have pledged to the Lord.^{[a] 34} But I say to you that you must not pledge at all. You must not pledge by heaven, because it’s God’s throne. ³⁵ You must not pledge by the earth, because it’s God’s footstool. You must not pledge by Jerusalem, because it’s the city of the great king. ³⁶ And you must not pledge by your head, because you can’t turn one hair white or black. ³⁷ Let your yes mean yes, and your no mean no. Anything more than this comes from the evil one.
