Genesis 42:1-6

Now Jacob saw that there was grain in Egypt, and Jacob said unto his sons, Why do ye look one upon another? And he said, Behold, I have heard that there is grain in Egypt: get you down thither, and buy for us from thence; that we may live, and not die. And Joseph’s ten brethren went down to buy grain from Egypt. But Benjamin, Joseph’s brother, Jacob sent not with his brethren; for he said, Lest peradventure harm befall him. And the sons of Israel came to buy among those that came: for the famine was in the land of Canaan. And Joseph was the governor over the land; he it was that sold to all the people of the land. And Joseph’s brethren came, and bowed down themselves to him with their faces to the earth.
