Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
Isaiah 1:18
The people of Israel are apostate, rebellious, and corrupt; only a few remain faithful—The people’s sacrifices and feasts are rejected—They are called upon to repent and work righteousness—Zion will be redeemed in the day of restoration.
