Jamieson, Fausset and Brown on Joshua 7:24-26

24-26. Joshua, and all Israel with him, took Achan--He with his children and all his property, cattle as well as movables, were brought into one of the long broad ravines that open into the Ghor, and after being stoned to death (Nu 15:30-35), his corpse, with all belonging to him, was consumed to ashes by fire. "All Israel" was present, not only as spectators, but active agents, as many as possible, in inflicting the punishment--thus testifying their abhorrence of the sacrilege, and their intense solicitude to regain the divine favor. As the divine law expressly forbade the children to be put to death for their father's sins (De 24:16), the conveyance of Achan's "sons and daughters" to the place of execution might be only as spectators, that they might take warning by the parental fate; or, if they shared his punishment (Jos 22:20), they had probably been accomplices in his crime, and, indeed, he could scarcely have dug a hole within his tent without his family being aware of it.
