Exodus 20:16

¹⁶ “You shall not bear false witness against your neighbor.

Matthew 5:33-37 | Oaths

³³ “Again you have heard that it was said to those of old, ‘You shall not swear falsely, but shall perform to the Lord what you have sworn.’ ³⁴ But I say to you, Do not take an oath at all, either by heaven, for it is the throne of God, ³⁵ or by the earth, for it is his footstool, or by Jerusalem, for it is the city of the great King. ³⁶ And do not take an oath by your head, for you cannot make one hair white or black. ³⁷ Let what you say be simply ‘Yes’ or ‘No’; anything more than this comes from evil.^[a]
