Flavius Josephus, Antiquities of the Jews
William Whiston, A.M., Ed.

[42] These intercessions Joshua put up to God, as he lay prostrate on his face: whereupon God answered him, That he should rise up, and purify his host from the pollution that had got into it; that "things consecrated to me have been impudently stolen from me," and that "this has been the occasion why this defeat had happened to them;" and that when they should search out and punish the offender, he would ever take care they should have the victory over their enemies. This Joshua told the people; and calling for Eleazar the high priest, and the men in authority, he cast lots, tribe by tribe; and when the lot showed that this wicked action was done by one of the tribe of Judah, he then again proposed the lot to the several families thereto belonging; so the truth of this wicked action was found to belong to the family of Zachar; and when the inquiry was made man by man, they took Achar, who, upon God's reducing him to a terrible extremity, could not deny the fact: so he confessed the theft, and produced what he had taken in the midst of them, whereupon he was immediately put to death; and attained no more than to be buried in the night in a disgraceful manner, and such as was suitable to a condemned malefactor.
