Listen now, king of Assyria! Because of all your evil boasting, the Lord, the LORD Almighty, will send a plague among your proud troops, and a flaming fire will ignite your glory.
The LORD, the Light of Israel and the Holy One, will be a flaming fire that will destroy them. In a single night he will burn those thorns and briers, the Assyrians.
Assyria's vast army is like a glorious forest, yet it will be destroyed. The LORD will completely destroy Assyria's warriors, and they will waste away like sick people in a plague.
Only a few from all that mighty army will survive -- so few that a child could count them!
Then at last those left in Israel and Judah will trust the LORD, the Holy One of Israel. They will no longer depend on the Assyrians, who would destroy them.
References for Isaiah 10:20
A remnant of them will return to the Mighty God.
References for Isaiah 10:21
But though the people of Israel are as numerous as the sand on the seashore, only a few of them will return at that time. The LORD has rightly decided to destroy his people.
Yes, the Lord, the LORD Almighty, has already decided to consume them.
So this is what the Lord, the LORD Almighty, says: "My people in Jerusalem, do not be afraid of the Assyrians when they oppress you just as the Egyptians did long ago.
References for Isaiah 10:24
It will not last very long. In a little while my anger against you will end, and then my anger will rise up to destroy them."
The LORD Almighty will beat them with his whip, as he did when Gideon triumphed over the Midianites at the rock of Oreb, or when the LORD's staff was raised to drown the Egyptian army in the sea.
