The Bible is it's own best Commentary. Cross reference the Jeremiah Quote with Isaiah 1:11-20.
Here's a brief commentary on the verses.

Is God finished with Israel? He denounces them as "Sodom and Gomorrah" (verse 10), judging their worship worthless, and their prayers an insult. But just when his tirade reaches its peak, God invites the Israelites to "come . . . reason" with him. Sins "like scarlet" shall be "as white as snow" (verse 18). God judges his people not to destroy them, but to bring them to repentance, forgiveness, and redemption.
