Isaiah 10:16-19. “Therefore shall the Lord, the Lord of hosts, send among his fat one leanness: and under his glory He shall kindle a burning like the burning of a fire..And the light of Israel shall be for a fire, and His Holy Ones for a flame: and it shall burn and devour his thorns and his briers in one day: And shall consume the glory of his forest, and of his fruitful field, both soul and body: and they shall be as when a standardbearer fainteth. And the rest of the trees of his forest shall be few, that a child may write them.”
The King of Assyria’s boasting will come to an end once God has accomplished His purpose. That end will not be pleasant.
Isaiah uses two titles to refer to God in verse 16. The first is simply the Lord (Ha-Adon), and is used b Isaiah always in connection with the power exerted judicially and penally. The second title, Adonai Sabaoth, “the Lord of Hosts”, is used here only, and indicates His absolute sovereignty over everything and everyone, including Assyria.
God is not to be trivialized. He is the Creator and Owner of all things. Those who look on Him with a dismissive attitude will be dealt with harshly.
The fat (powerful, wealthy) men of Assyria would become thin with poverty and hunger. In verse 17, God is “The Light of Israel” and “His Holy one.” He would be a consuming fire, making a bonfire of the mighty ones as if they were nothing more than briers and thorns. The armed forces, “the glory of his forest and of his fruitful field,” would be consumed “from the soul even to the flesh,” completely demolished. Verse 19 describes the scattered remnants of the army that march against Jerusalem, so few that a boy could easily count them. The angel of the Lord killed 185,000 of the Assyrian army in one night, and few were left (Is.37:36-38; 2 Kings 19:35).
