Ezekiel 22:21-22

“Yes, I will gather you and blow on you with the fire of my wrath, and you will be melted in its midst. As silver is melted in the midst of the furnace, so will you be melted in its midst. And you will know that I Yahweh have poured out my fury on you.”

It is now reiterated and emphasised that the house of Israel in Jerusalem/Judah are like the dross of metals in the midst of the furnace where the silver is purified. Ezekiel is thinking of them as impure, unrefined silver ore, indeed the dross within that silver.

All Levels of People Are Included in Jerusalem's Condemnation.

In this oracle prophets, priests, princes and the people of the land are all indicted for their evil behaviour.
