And I will restore thy judges as at the first, and thy counsellors as at the beginning: afterward thou shalt be called, The city of righteousness, the faithful city. (Isaiah 1:26)
The prophet looks forward to a time when there would again be faithful judges like Samuel, David, and Solomon. Israel would be an ideal state with ideal rulers.
The faithful city.
There will be a Jerusalem marked by righteousness only when the New Jerusalem comes down from heaven after the thousand years (Rev. 21:1, 2). Then the city will be ruled by Jesus, the Son of David, who will “execute judgment and righteousness,” and the ideal city, no less than its righteous King, will be called “the Lord our righteousness,” (Jer. 33:15, 16; cf. Eze. 48:35).
