34 But I tell you, Swear not at all; neither by heaven, for it is God's throne;
35 nor by the earth, for it is his footstool, nor by Jerusalem, for it is the city of the great King;
36 nor swear by your head, for you cannot make one hair white or black.
37 But let your speech be, yes, yes, and no, no; for any thing more than this is evil.
