'Bellows' in the Bible

The fiery bellows of judgment burn fiercely. But there is too much dross to be removed. The process of refining them has proved useless. The wicked have not been purged.

The Lord roars from Zion; from Jerusalem his voice bellows out. The heavens and the earth shake. But the Lord is a refuge for his people; he is a stronghold for the citizens of Israel.
