Matthew Poole and continuators on Joshua 10:36

36 And Joshua went up from Eglon, and all Israel with him unto Hebron , and they fought against it.

Which though they took and killed all its Inhabitants, yet they did not keep it; and therefore when Joshua and his Army had forsaken it, and were returned to Gilgal, it seems the Giants and other Canaanites being burnt out, or driven away from their former seats, planted and fortified themselves there; which made it necessary for Caleb to take it a second time, as is recorded Iosh. 15. 14. Iudg. 1. 10. Or, this is the same Story, and the same Conquest of Hebron which is here generally related, and afterwards repeated, and more particularly described, Iosh. 15. 13, 14.
