Genesis 42:5-13

So the sons of Israel came to buy grain among those who were coming, for the famine was in the land of Canaan also. Now Joseph was the ruler over the land; he was the one who sold to all the people of the land. And Joseph’s brothers came and bowed down to him with their faces to the ground. When Joseph saw his brothers he recognized them, but he disguised himself to them and spoke to them harshly. And he said to them, “Where have you come from?” And they said, “From the land of Canaan, to buy food.” But Joseph had recognized his brothers, although they did not recognize him. Joseph remembered the dreams which he had about them, and said to them, “You are spies; you have come to look at the undefended parts of our land.” Then they said to him, “No, my lord, but your servants have come to buy food. We are all sons of one man; we are honest men, your servants are not spies.” Yet he said to them, “No, but you have come to look at the undefended parts of our land!” But they said, “Your servants are twelve brothers in all, the sons of one man in the land of Canaan; and behold, the youngest is with our father today, and one is no longer alive.”
