Isaiah 48:18-20

New Revised Standard Version, Anglicised Catholic Edition

¹⁸ O that you had paid attention to my commandments!
    Then your prosperity would have been like a river,
    and your success 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.
