Genesis 42:6-17

Now Joseph was governor over the land; and it was he who sold to all the people of the land. And Joseph’s brothers came and bowed down before him with their faces to the earth. Joseph saw his brothers and recognized them, but he acted as a stranger to them and spoke roughly to them. Then he said to them, “Where do you come from?” And they said, “From the land of Canaan to buy food.” So Joseph recognized his brothers, but they did not recognize him. Then Joseph remembered the dreams which he had dreamed about them, and said to them, “You are spies! You have come to see the nakedness of the land!” And they said to him, “No, my lord, but your servants have come to buy food. We are all one man’s sons; we are honest men; your servants are not spies.” But he said to them, “No, but you have come to see the nakedness of the land.” And they said, “Your servants are twelve brothers, the sons of one man in the land of Canaan; and in fact, the youngest is with our father today, and one is no more.” But Joseph said to them, “It is as I spoke to you, saying, ‘You are spies!’ In this manner you shall be tested: By the life of Pharaoh, you shall not leave this place unless your youngest brother comes here. Send one of you, and let him bring your brother; and you shall be kept in prison, that your words may be tested to see whether there is any truth in you; or else, by the life of Pharaoh, surely you are spies!” So he put them all together in prison three days.
