Cyril of Alexandria : This means that he is teaching here about the ones who were swarming and absorbing it, those who had taken it over. For almost like wild beasts they had reduced and absorbed it. He shows here that the number of those called are so many that they are without number. For his children, it says, that you have lost have pleaded in your ear, "Make room for me." — COMMENTARY ON Isaiah 4:4.49:19-21
