Jeremiah 33:16

Then Judah would enjoy salvation, and Jerusalem would dwell in safety. The name of the city would be "Yahweh our righteousness." Formerly this was to be the name of a ruler (Jeremiah 23:6), but it will also be the name of Jerusalem (cf. Ezekiel 48:35). Righteous Messiah would bring righteousness to the city and make its people righteous. [Note: Keil, 2:72.]

"The inference is that Jerusalem would so manifest the qualities of justice and righteousness (in contrast to her past bad record) that she would be worthy of such a name and exemplify the divine order for all the cities and all the people in Israel." [Note: Thompson, p. 601.]
