Genesis 42:5

³  And Joseph's ten brethren went down to buy corn in Egypt.

⁴  But Benjamin, Joseph's brother, Jacob sent not with his brethren; for he said, Lest peradventure mischief befall him.

⁵  And the sons of Israel came to buy corn among those that came: for the famine was in the land of Canaan.

⁶  And Joseph was the governor over the land, and he it was that sold to all the people of the land: and Joseph's brethren came, and bowed down themselves before him with their faces to the earth.

⁷  And Joseph saw his brethren, and he knew them, but made himself strange unto them, and spake roughly unto them; and he said unto them, Whence come ye? And they said, From the land of Canaan to buy food.
