'Purging' in the Bible

He burned the bones of the priests on their altars, thus purging Judah and Jerusalem.

When thou hast ended purging it, thou shalt present a young bullock without blemish, and a ram out of the flock without blemish;

Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?

for he with whom these things are not present is blind, short-sighted, and has forgotten the purging of his former sins.
