Genesis 42:8-13

And Joseph recognized his brothers, but they did not recognize him. And Joseph remembered the dreams that he had dreamed of them. And he said to them, “You are spies; you have come to see the nakedness of the land.” They said to him, “No, my lord, your servants have come to buy food. We are all sons of one man. We are honest men. Your servants have never been spies.” He said to them, “No, it is the nakedness of the land that you have come to see.” And they said, “We, your servants, are twelve brothers, the sons of one man in the land of Canaan, and behold, the youngest is this day with our father, and one is no more.”
