Isaiah 7:16-20

For before the child is that old, the lands of the two kings you fear so much will both be deserted. “Then the LORD will bring things on you, your nation, and your family unlike anything since Israel broke away from Judah. He will bring the king of Assyria upon you!” In that day the LORD will whistle for the army of southern Egypt and for the army of Assyria. They will swarm around you like flies and bees. They will come in vast hordes and settle in the fertile areas and also in the desolate valleys, caves, and thorny places. In that day the Lord will hire a “razor” from beyond the Euphrates River—the king of Assyria—and use it to shave off everything: your land, your crops, and your people.
