Albert Barnes Commentary Joshua 10:11

"And it came to pass, as they fled from before Israel, while they were at the descent of Beth-horon, that Jehovah cast down great stones from heaven upon them unto Azekah, and they died: they were more who died with the hailstones than they whom the children of Israel slew with the sword." — Joshua 10:11 (ASV)

Compare Ecclesiasticus 46:6. Frightful storms occasionally sweep over the hills of Judea; but this was evidently a miraculous occurrence, like the hail which struck Egypt (Exodus 9:24) and the tempest which fell on the Philistines at Ebenezer (1 Samuel 7:10).
