Jeremiah 23:6

In His days Judah shall be saved and Israel shall dwell safely. And this is His name whereby He shall be called, The Lord our, Righteousness. Here the Messiah is spoken of by a name, in a figure, which is used also by Isaiah and Zechariah. To David, namely, as a descendant of Judah, as a member of his family, Jehovah will cause to arise a righteous Branch, a shoot characterized by, and distinguished for, righteousness. This Branch will at the same time be a King, who would have royal power and would make use of that power and authority in taking care of the affairs of His kingdom in a prudent manner. The excellency of His rule would be brought out particularly by the fact that He would perform judgment and execute righteousness according to unquestioned standards, although unusual in the eyes of men. For He would show these traits in bringing salvation to Judah and in letting Israel dwell in safety, both expressions referring to the true spiritual Israel, the Church of Christ. No wonder, then, that His name would be called "Jehovah Our Righteousness," since, by virtue of His perfect atonement, all men may become partakers of the righteousness earned by Him for them.
