Matthew 5:33–37

“Again you have heard that it was said to those of old, ‘You shall not swear falsely, but shall perform to the Lord what you have sworn.’ But I say to you, Do not take an oath at all, either by heaven, for it is the throne of God, or by the earth, for it is his footstool, or by Jerusalem, for it is the city of the great King. And do not take an oath by your head, for you cannot make one hair white or black. Let what you say be simply ‘Yes’ or ‘No’; anything more than this comes from evil.

“Again, you have heard that it was said to the people long ago, ‘Do not break your oath, but fulfill to the Lord the vows you have made.’ But I tell you, do not swear an oath at all: either by heaven, for it is God’s throne; or by the earth, for it is his footstool; or by Jerusalem, for it is the city of the Great King. And do not swear by your head, for you cannot make even one hair white or black. All you need to say is simply ‘Yes’ or ‘No’; anything beyond this comes from the evil one.

“Again, you have heard that it was said to our ancestors, You must not break your oath, but you must keep your oaths to the Lord. But I tell you, don’t take an oath at all: either by heaven, because it is God’s throne; or by the earth, because it is his footstool; or by Jerusalem, because it is the city of the great King. Do not swear by your head, because you cannot make a single hair white or black. But let your ‘yes’ mean ‘yes,’ and your ‘no’ mean ‘no.’ Anything more than this is from the evil one.

“You have also heard that our ancestors were told, ‘You must not break your vows; you must carry out the vows you make to the Lord.’ But I say, do not make any vows! Do not say, ‘By heaven!’ because heaven is God’s throne. And do not say, ‘By the earth!’ because the earth is his footstool. And do not say, ‘By Jerusalem!’ for Jerusalem is the city of the great King. Do not even say, ‘By my head!’ for you can’t turn one hair white or black. Just say a simple, ‘Yes, I will,’ or ‘No, I won’t.’ Anything beyond this is from the evil one.

“Again you have heard that it was said to the people of old, ‘Do not swear falsely, but fulfill your oaths to the Lord.’ But I say to you, do not swear at all, either by heaven, because it is the throne of God, or by the earth, because it is the footstool of his feet, or by Jerusalem, because it is the city of the great king. And do not swear by your head, because you are not able to make one hair white or black. But let your statement be ‘Yes, yes; no, no,’ and anything beyond these is from the evil one.

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: 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. Neither shalt thou swear by thy head, because thou canst not make one hair white or black. But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.
