Genesis 47:4

And they said to Pharao, We are come to sojourn in the land, for there is no pasture for the flocks of thy servants, for the famine has prevailed in the land of Chanaan; now then, we will dwell in the land of Gesem. And Pharao said to Joseph, Let them dwell in the land of Gesem; and if thou knowest that there are among them able men, make them overseers of my cattle. So Jacob and his sons came into Egypt, to Joseph; and Pharao, king of Egypt, heard of it.
