|Matthew 5: 33 - 37
||"Again you have heard that it was said to the men of old, `You shall not swear falsely, but shall perform to the Lord what you have sworn.'
||But I say to you, Do not swear 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 swear 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.
