The house of Israel is to me become dross - They are all like base metal - brass, tin, iron, and lead alloyed together with silver. Ye must be put in the furnace, and subjected to the most intense fire, till your impurities are consumed away. No ordinary means will avail any thing; the most violent must be resorted to.
The fifth word of judgment. The furnace. In the besieged city the people shall be tried and purged.
Dross - A frequent metaphor which denotes not only the corruption of the people, who have become like base metal, but also a future purification whereby, the “dross” being burned away, the remnant of good may appear.
