Genesis 42:6-9 NKJV

⁶ 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. ⁷ 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.” ⁸ So Joseph recognized his brothers, but they did not recognize him. ⁹ 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!”
