'Melting' in the Bible

like the gathering of silver and bronze and iron and lead and tin to the middle of a furnace to blow fire on it for melting. Thus I will gather in my anger and in my rage, and I will {deposit} you, and I will melt you.

like melting silver at the center of a furnace. When you've been melted from the center out, then you'll know that I am the LORD. I'll pour out my anger on you.'"
