“Therefore,
The Sovereign,
Yahweh of hosts,
The Mighty One of Israel
Says.
‘O!
I will pour out my wrath
On my enemies!
I will avenge myself
On my foes!
I will turn my hand
Against you!
I will smelt away your dross
As with lye!
I will remove your entire alloy!’”
Now we have another oracle of Yahweh, the sovereign, Mighty One of Israel, via Isaiah. Yahweh, in the first person singular, was going to pour out his wrath on his enemies and bring revenge on his foes. He also was going to turn his hand against his own people by melting them down with lye so that they would be noting but worthless scum dross. He was going to take away all their alloys. This is an interesting description of God taking the Israelites apart.
