Isaiah 51:1-2

Revised Standard Version

51 “Hearken to me, you who pursue deliverance,
    you who seek the Lord;
look to the rock from which you were hewn,
    and to the quarry from which you were digged.
² Look to Abraham your father
    and to Sarah who bore you;
for when he was but one I called him,
    and I blessed him and made him many.
