Come on, let's argue this out, says the Lord. Even though your sins are like scarlet, they will become white like snow. Even though they are red like crimson, they will become like wool.
the priest shall have two ceremonially clean birds brought to him, with some cedar wood, crimson thread, and hyssop, on behalf of the person to be made clean.
He will take the live bird together with the cedar wood, crimson thread, and hyssop, and dip them in the blood of the bird that was killed over the fresh water.
