TSK · Genesis 47:1

and thou shalt dwell in the land of Goshen, and thou shalt be near unto me, thou, and thy children, and thy children's children, and thy flocks, and thy herds, and all that thou hast:

And he sent Judah before him unto Joseph, to show the way before him unto Goshen; and they came into the land of Goshen.

that ye shall say, Thy servants have been keepers of cattle from our youth even until now, both we, and our fathers: that ye may dwell in the land of Goshen; for every shepherd is an abomination unto the Egyptians.

Only in the land of Goshen, where the children of Israel were, was there no hail.
