The children which you shall have, after you have lost the other, shall say again in your ears, The place is too narrow for me: give a place to me that I may dwell.
Read Chapter 49
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 18.104.22.168–21"
