Matthew 5:33-37

New Revised Standard Version Catholic Edition

Concerning Oaths

³³ “Again, you have heard that it was said to those of ancient times, ‘You shall not swear falsely, but carry out the vows you have made to the Lord.’ ³⁴ But I say to you, Do not swear 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 swear by your head, for you cannot make one hair white or black. ³⁷ Let your word be ‘Yes, Yes’ or ‘No, No’; anything more than this comes from the evil one.^[a]
