Jesus Teaches About Making Promises

³³ “You have heard that it was said to our people long ago, ‘When you make a vow, you must not break your promise. Keep the vows that you make to the Lord.’^{[a] 34} But I tell you, when you make a promise, don’t try to make it stronger with a vow. Don’t make a vow using the name of heaven, because heaven is God’s throne. ³⁵ Don’t make a vow using the name of the earth, because the earth belongs to him.^[b] Don’t make a vow using the name of Jerusalem, because it also belongs to him, the great King. ³⁶ And don’t even say that your own head is proof that you will keep your promise. You cannot make one hair on your head white or black. ³⁷ Say only ‘yes’ if you mean ‘yes,’ and say only ‘no’ if you mean ‘no.’ If you say more than that, it is from the Evil One.
