Joshua 8:2

To Ai, i.e. the city and people of Ai. As thou didst unto Jericho and her king, i.e. overcome and destroy them. This was enjoined, partly to chastise their last insolence, and the triumphs and blasphemies which doubtless their success produced; and partly to revive the dread and terror which had been impressed upon the Canaanites by Jericho's ruin, and had been much abated by the late success of Ai, and their confidence and expectation of further and greater success much raised.
