He therefore cried, Cause every man to go out from me That is, all the Egyptians, for he would not have them to be acquainted with the guilt of his brethren, whose reputation he wished to preserve: nor would he have any restraint on those affections and tears which he could no longer repress. How must it have amazed Judah and his brethren, who were waiting for an answer, to discover in him, instead of the gravity of a judge, the natural affection of a father or brother!
