Genesis 41:46-49

Joseph was thirty years old when he entered the service of Pharaoh king of Egypt. And Joseph went out from the presence of Pharaoh and went through all the land of Egypt. During the seven plentiful years the earth produced abundantly, and he gathered up all the food of these seven years, which occurred in the land of Egypt, and put the food in the cities. He put in every city the food from the fields around it. And Joseph stored up grain in great abundance, like the sand of the sea, until he ceased to measure it, for it could not be measured.
