All Commentaries on Exodus 8:2 Go To Exodus 8

For what reason do you puff yourself up with human pride? A man insulted you, and you swelled up and were angered. Rid yourself of the fleas that you may sleep. Find out who you are! For that you may know, brothers, that these things which would bother us were created to enable us to control our pride, [remember], God could have tamed the proud people of Pharaoh with bears, with lions or with snakes; he sent flies and frogs upon them that their pride might be tamed by the most ignoble of things.
