Because (Achan) confessed before the Name of the Holy One, blessed be He, he has a portion in the world to come, as it is said, "And Joshua said, Why hast thou troubled us? The Lord shall trouble thee this day" (Josh. 7:25). "This day" thou art troubled, but thou shalt not be troubled in the future world.
Know thou the power of the ban. Come and see from the (story of) the tribes, who were zealous because of immorality against || the tribe of Benjamin. The Holy One, blessed be He, said to them: Ye are zealous because of the immorality, and ye are not zealous because of the image of Micah. Therefore the Benjamites slew some of them a first and a second and a third time, until they went before the Ark of the Covenant of the Lord seeking repentance, and they were forgiven. They decreed that all Israel should (make peace) with them, and they repented both old and young, as it is said, "For they made a great oath concerning him that came not up unto the Lord to Mizpah" (Judg. 21:5). Did all Israel take an oath? But the ban is the same as the oath.
