Matthew 5:34-37

5:34 But I say to you, do not take oaths at all – not by heaven, because it is the throne of God, 5:35 not by earth, because it is his footstool, and not by Jerusalem, because it is the city of the great King. 5:36 Do not take an oath by your head, because you are not able to make one hair white or black. 5:37 Let your word be ‘Yes, yes’ or ‘No, no.’ More than this is from the evil one.
