I will call them my people, who were not my people; and her beloved, who was not beloved.
All Commentaries on Romans 9:25 Go To Romans 9
Irenaeus of Lyons
AD 202
And proclaim in what sense .
and Him who, by His Son Christ Jesus, has called us to the knowledge of Himself, from the worship of stones, so that those who were not a people were made a people, and she beloved who was not beloved.
And it shall come to pass, that in the place where it was said, This is not a people, there shall they be called the children of the living God."
