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.^[a] 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.
