The sin had been national (Joshua 7:1 note), and accordingly the expiation of it was no less so. The whole nation, no doubt through its usual representatives, took part in executing the sentence. Achan had fallen by his own act under the ban Joshua 6:18, and consequently he and his were treated as were communities thus devoted Deuteronomy 13:15-17. It would appear too that Achan’s family must have been accomplices in his sin; for the stolen spoil could hardly have been concealed in his tent without their being privy thereto.
