The brothers before Joseph

6 And Joseph was governor in the land of Egypt, and corn was sold by his direction to the people. And when his brethren had bowed down to him, 7 And he knew them, he spoke as it were to strangers, somewhat roughly, asking them: Whence came you? They answered: From the land of Chanaan, to buy necessaries of life. 8 And though he knew his brethren, he was not known by them.
