The lot being appealed to (Pr 16:33), he proceeded in the inquiry from heads of tribes to heads of families, and from heads of households in succession to one family, and to particular persons in that family, until the criminal was found to be Achan, who, on Joshua's admonition, confessed the fact of having secreted for his own use, in the floor of his tent, spoil both in garments and money [Jos 7:19-21]. How dreadful must have been his feelings when he saw the slow but certain process of discovery! (Nu 32:23).
