Achan
    called also Achar, i.e., one who troubles (1 Chr. 2:7), in
    commemoration of his crime, which brought upon him an awful
    destruction (Josh. 7:1). On the occasion of the fall of Jericho,
    he seized, contrary to the divine command, an ingot of gold, a
    quantity of silver, and a costly Babylonish garment, which he
    hid in his tent. Joshua was convinced that the defeat which the
    Israelites afterwards sustained before Ai was a proof of the
    divine displeasure on account of some crime, and he at once
    adopted means by the use of the lot for discovering the
    criminal. It was then found that Achan was guilty, and he was
    stoned to death in the valley of Achor. He and all that belonged
    to him were then consumed by fire, and a heap of stones was
    raised over the ashes.
