Matthew 5:34-37 ▼

34 but I say to you not to swear at all; neither by Heaven, because it is the throne of God,

35 nor by the earth, because it is His footstool, nor by Jerusalem, because it is [the] city of [the] great King,

36 nor may you swear by your head, because you are not able to make one hair white or black;

37 but let your word be, Yes, Yes, No, No, and that which is more than these is of the evil [one].
