Matthew:5:34-36
nkjv@Matthew:5:34 @ But I say to you, do not swear at all: neither by heaven, for it is God's throne;
nkjv@Matthew:5:35 @ nor by the earth, for it is His footstool; nor by Jerusalem, for it is the city of the great King.
nkjv@Matthew:5:36 @ Nor shall you swear by your head, because you cannot make one hair white or black.
