Matthew 5:36

Modern English Version

Nor shall you swear by your head, because you cannot make one hair white or black.

See the chapter Copy

nor by the earth, for it is His footstool; nor by Jerusalem, for it is the city of the great King.

But let your ‘Yes’ mean ‘Yes,’ and ‘No’ mean ‘No.’ For whatever is more than these comes from the evil one.

Who among you by taking thought can add one cubit to his stature?

Who of you by worrying can add one cubit to his height?
