'Fiery' in the Bible

Because of that, the Lord, the God who rules over all, said to me, "Because these people have spoken like this, I will make the words that I put in your mouth like fire. And I will make this people like wood which the fiery judgments you speak will burn up."

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.
