Genesis 42:8-13

Joseph knew they were his brothers, but they did not know who he was. And Joseph remembered his dreams about his brothers bowing to him. He said to them, “You are spies! You came to learn where the nation is weak!” But his brothers said to him, “No, my master. We come as your servants just to buy food. We are all sons of the same father. We are honest men, not spies.” Then Joseph said to them, “No! You have come to learn where this nation is weak!” And they said, “We are ten of twelve brothers, sons of the same father, and we live in the land of Canaan. Our youngest brother is there with our father right now, and our other brother is gone.”
