Isaiah 1:18-20

Revised Standard Version Catholic Edition

¹⁸ “Come now, let us reason together,
    says the Lord:
though your sins are like scarlet,
    they shall be as white as snow;
though they are red like crimson,
    they shall become like wool.
¹⁹ If you are willing and obedient,
    you shall eat the good of the land;
²⁰ but if you refuse and rebel,
    you shall be devoured by the sword;
    for the mouth of the Lord has spoken.”
