Genesis 42:7-9

Darby Translation

⁷ And Joseph saw his brethren, and knew them; but he made himself strange to them, and spoke roughly to them, and said to them, Whence come ye? And they said, From the land of Canaan, to buy food.

⁸ And Joseph knew his brethren, but they did not know him.

⁹ And Joseph remembered the dreams that he had dreamt of them; and he said to them, Ye are spies: to see the exposed places of the land ye are come.
