Isaiah 48:17-19

New Catholic Bible

¹⁷ Thus says the Lord God,
    your redeemer, the Holy One of Israel:
I am the Lord, your God
    who teaches you what is for your own good
    and who leads you in the way you should go.
¹⁸ If only you had listened to my commandments,
    your prosperity would have been like a river
    and your success like the waves of the sea.
¹⁹ Your descendants would have been as numerous as the sand
    and your offspring like its countless grains.
Their name would never be erased
    or blotted out from my sight.
