Genesis 34:27-29

‘The sons of Jacob came on the slain and spoiled the city because they had defiled their sister. They took their flocks and their herds and their asses, and whatever was in the city and whatever was in the surrounding country. And all their wealth and all their little ones, and their wives, they took captive, and spoiled even all that was in the house.'

Once the expiation had been carried out the remainder of Jacob's sons moved in to plunder the city. They despoiled the city and took possession of all the belongings of the inhabitants, including their wives and children. And the reason is again made clear. It was due to their sacrilege.
