Isaiah 51:1-2

New Revised Standard Version, Anglicised

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