Isaiah 48:17-19

Revised Standard Version Catholic Edition

¹⁷ Thus says the Lord,
    your Redeemer, the Holy One of Israel:
“I am the Lord your God,
    who teaches you to profit,
    who leads you in the way you should go.
¹⁸ O that you had hearkened to my commandments!
    Then your peace would have been like a river,
    and your righteousness like the waves of the sea;
¹⁹ your offspring would have been like the sand,
    and your descendants like its grains;
their name would never be cut off
    or destroyed from before me.”
