Charles Ellicott Commentary 2 Chronicles 19:5

"And he set judges in the land throughout all the fortified cities of Judah, city by city," — 2 Chronicles 19:5 (ASV)

And he set. — Appointed, or stationed.

The fenced cities. —As being the chief centres of each district.

City by city. — For every city, according to the Law, Deuteronomy 16:18, in all thy gates. (Compare to 1 Chronicles 23:4; 1 Chronicles 26:29.) The judges would be Levites, and probably also priests and family chiefs, as in the case of Jerusalem (2 Chronicles 19:8).
