'Cleanse' in the Bible

At that time shall it be said to this people and to Jerusalem, "A hot wind from the bare heights in the wilderness toward the daughter of my people, not to winnow, nor to cleanse;

I will cleanse them from all their iniquity, by which they have sinned against me; and I will pardon all their iniquities, by which they have sinned against me, and by which they have transgressed against me.
