Joshua 8:17
men <0376> [a man.]
Bethel <01008> [Bethel.]
Bethel is not mentioned in the Greek version, and some, with Houbigant and Pilkington, think it was not originally in the Hebrew; because, had the men of Bethel pursued, as well as those of Ai, it would have been said that they left the cities, and not the city, open. The principal strength of Bethel might have been previously taken into Ai, as the strongest place to make a stand in; Bethel being but about three miles westward from Ai.
