Midrash su Genesi 41:51

And the boys grew up and they followed his ways and his instructions. They did not turn ‎neither to the right nor to the left from the path pointed out by their father. And the Lord was ‎with them and they had understanding, and they were versed in all wisdom and all the affairs ‎of the government. And all the princes of the king and the prominent inhabitants of Egypt ‎praised those boys, and they grew up amidst the sons of the king. And the seven years of ‎plenty that were throughout the land were at an end, and after them came seven years of ‎famine as Joseph had spoken, and the famine was in all the earth. And when the people of ‎Egypt saw that the famine had commenced throughout the land, they opened all their ‎storehouses of corn, for the famine grew very powerful upon them. And they found all the ‎food in their treasuries full of worms unfit for food. And the famine grew stronger in all the ‎land, and the inhabitants of Egypt came and cried out before Pharaoh, for the famine was ‎heavy upon them, and they said unto Pharaoh: Give food unto thy servants and let us not ‎starve before thine eyes, we and our children. And Pharaoh answered them saying: And why ‎are you crying unto me? Behold during the seven years of plenty Joseph hath commanded you ‎to gather up corn for the years of famine, and wherefore have you not hearkened unto his ‎voice. And the Egyptians answered unto the king: As thy soul liveth, oh our lord, whatsoever ‎Joseph hath spoken thy servants hath done. For verily thy servants hath gathered up all the ‎food of their fields, in the seven years of plenty and we hath placed it into our treasuries even ‎to this day. And when the famine grew powerful upon thy servants we opened our treasuries, ‎and behold all our food is full of worms unfit to eat. And when the king heard all that had ‎befallen the inhabitants of Egypt, the king was exceedingly afraid and terrified on account of ‎the famine, and the king answered unto the people saying: Since this has occurred unto you, ‎go ye unto Joseph and do whatsoever he will say unto you. Do not disobey his words. And all ‎the Egyptians went and came before Joseph and they said unto him: Give us food, and ‎wherefore shall we die of hunger before thee, for behold we have gathered up our produce ‎during the seven years as thou hast commanded, and we placed it into the store houses, and ‎now such and such hath happened unto us. And when Joseph heard the words of the ‎Egyptians and what had befallen them, Joseph opened the stores of his food and he sold it ‎unto the Egyptians. And the famine was upon the face of the whole earth, in the other lands ‎as well as in Egypt. And in Egypt alone was food for sale and all the inhabitants of Egypt came ‎unto Joseph to buy their food, for the famine was powerful over them and all their produce ‎had been spoilt. And Joseph sold it unto all the Egyptians day after day. And all the inhabitants ‎of the land of Canaan, and the Philistines, and those on the other side of Jordan, and the sons ‎of the east and of all the cities of the earth far and near heard that there was corn for sale in ‎Egypt, and all of them came into Egypt to purchase for the famine was heavy upon them.‎
