John Wesley on Jeremiah 23:6

Judah - During the reign and kingdom of the Messiah the people of God typified by Judah and Israel shall be saved with a spiritual salvation, and God will be a special protection to them. And this - The name wherewith this branch shall be called, shall be, The Lord our righteousness. This place is an eminent proof of the Godhead of Christ, he is here called Jehovah, and what is proper to God alone, namely to justify, is here applied to Christ. He who knew no sin, was made sin, (that is, a sacrifice for sin) for us, that we might be made, the righteousness of God in him.
