Genesis 41:46-49

Now Joseph was thirty years old when he stood before Pharaoh, king of Egypt. And Joseph went out from the presence of Pharaoh and went through all the land of Egypt. During the seven years of plenty the land brought forth abundantly. So he gathered all the food of these seven years which occurred in the land of Egypt and placed the food in the cities; he placed in every city the food from its own surrounding fields. Thus Joseph stored up grain in great abundance like the sand of the sea, until he stopped measuring it, for it was beyond measure.
