And Moses and Aaron were brought again unto Pharaoh,.... Upon this motion of his ministers, messengers were sent to bring them in again: and he said, go, serve the Lord your God; as you have often desired: but who are they that shall go? or, "who and who" (f)? for Pharaoh was unwilling that they should all go, but would have some retained as pledges of their return; for he was jealous of a design to get out of his country, and never return again, which he could not bear the thoughts of, even of losing such a large number of men he had under his power, and from whom he received so much profit and advantage by their labour. (f) "qui et qui?" Pagninus, Montanus; "quis & quis?" Vatablus.
