Genesis 41:46-49

He was thirty years old when he began serving in the court of Pharaoh, the king of Egypt. And when Joseph left Pharaoh’s presence, he inspected the entire land of Egypt. As predicted, for seven years the land produced bumper crops. During those years, Joseph gathered all the crops grown in Egypt and stored the grain from the surrounding fields in the cities. He piled up huge amounts of grain like sand on the seashore. Finally, he stopped keeping records because there was too much to measure.
