Libnah revolted - Libnah being toward the southwest of Palestine Joshua 15:42, its revolt cannot well have had any direct connection with that of Edom. It had been the capital of a small Canaanite state under a separate king before its conquest by Joshua Joshua 10:30; Joshua 12:15, and may perhaps always have retained a considerable Canaanite population. Or its loss may have been connected with the attacks made by the Philistines on Jehoram’s territories 2 Chronicles 21:16-17.
