Genesis 42:6-8

Darby Translation

⁶ And Joseph, he was the governor over the land—he it was that sold [the corn] to all the people of the land. And Joseph's brethren came and bowed down to him, the face to the earth.

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.
