33Again, you heard that it was said to those of old: "You shall not swear falsely, but you shall pay to the Lord what you have vowed."34But I say to you, do not swear at all—not by heaven, for it is God's throne;35nor by the earth, for it is his footstool; nor by Jerusalem, for it is the city of the great King;36nor by your head, for you cannot make one hair white or black.37But let your word be "Yes, yes; No, no." But what is more than these is from the evil one.
