He recognized it and said, “It is my son’s tunic. A wild animal has devoured him; Joseph is without doubt torn in pieces!”

Now [in the course of time] there was no food in all the land, for the famine was distressingly severe, so that the land of Egypt and all the land of Canaan languished [in destitution and starvation] because of the famine.
