Matthew 5:35 ASV

³³  Again, ye have heard that it was said to them of old time, Thou shalt not forswear thyself, but shalt perform unto the Lord thine oaths:

³⁴  but I say unto you, swear not at all; neither by the heaven, for it is the throne of God;

³⁵  nor by the earth, for it is the footstool of his feet; nor by Jerusalem, for it is the city of the great King.

³⁶  Neither shalt thou swear by thy head, for thou canst not make one hair white or black.

³⁷  But let your speech be, Yea, yea; Nay, nay: and whatsoever is more than these is of the evil 'one'.
