Genesis 41:46-49

Joseph was thirty years old when he entered the service of Pharaoh king of Egypt. And Joseph went out from Pharaoh’s presence and traveled throughout Egypt. During the seven years of abundance the land produced plentifully. Joseph collected all the food produced in those seven years of abundance in Egypt and stored it in the cities. In each city he put the food grown in the fields surrounding it. Joseph stored up huge quantities of grain, like the sand of the sea; it was so much that he stopped keeping records because it was beyond measure.
