Fought against Libnah - This city was near Makkedah, see Joshua 15:42, and fell to the tribe of Judah, Joshua 10:20, Joshua 10:42, and was given to the priests, Joshua 21:13. Sennacherib besieged it, after he had been obliged to raise the siege of Lachish. See 2 Kings 19:8; Isaiah 37:8.
Libnah - The word means “white” or “distinct,” and undoubtedly points to some natural feature of the spot, perhaps the “Garde Blanche” of the Crusaders, a castle which stood on or near the white cliffs which bound the plain of Philistia to the east opposite to Ascalon. It was in the southern part of the hill-country of Judah Joshua 15:42, and was one of the cities afterward assigned to the priests Joshua 21:13.
