And Jakob said, Accursed was the town of Shekem, when they entered within it to destroy it in their violent wrath; and their hatred against Joseph, for it was relentless. If, said Jakob, they dwell together, no king nor ruler may stand before them. Therefore will I divide the inheritance of the sons of Shimeon into two portions; one part shall come to them out of the inheritance of the sons of Jehuda, and one part from among the rest of the tribes of Jakob; and the tribe of Levi I will disperse among all the tribes of Israel.
