Matthew 5:33-37
Oaths
5:33 “Again, you have heard that it was said to an older generation, ‘Do not break an oath, but fulfill your vows to the Lord.’
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.
Matthew 23:16-22
23:16 “Woe to you, blind guides, who say, ‘Whoever swears by the temple is bound by nothing. But whoever swears by the gold of the temple is bound by the oath.’
23:17 Blind fools! Which is greater, the gold or the temple that makes the gold sacred?
23:18 And, ‘Whoever swears by the altar is bound by nothing. But if anyone swears by the gift on it he is bound by the oath.’
23:19 You are blind! For which is greater, the gift or the altar that makes the gift sacred?
23:20 So whoever swears by the altar swears by it and by everything on it.
23:21 And whoever swears by the temple swears by it and the one who dwells in it.
23:22 And whoever swears by heaven swears by the throne of God and the one who sits on it.
