Matthew 5:37 BBE

³⁵  Or by the earth, because it is the resting-place for his foot; or by Jerusalem, because it is the town of the great King.

³⁶  You may not take an oath by your head, because you are not able to make one hair white or black.

³⁷  But let your words be simply, Yes or No: and whatever is more than these is of the Evil One.

³⁸  You have knowledge that it was said, An eye for an eye, and a tooth for a tooth:

³⁹  But I say to you, Do not make use of force against an evil man; but to him who gives you a blow on the right side of your face let the left be turned.
