Isaiah 7:16-20

Yet even before that time comes for him to know good and evil, the lands of those two kings you dread will be deserted.” “The Lord YAHWEH is going to bring days of catastrophic trouble—on you, on your people, and on the whole royal court—not seen since the northern kingdom of Israel broke off from Judah. He is going to bring the king of Assyria with his great army!” In that day, the Lord YAHWEH will whistle and call for flies from Egypt’s lower streams. He will whistle for bees from the land of Assyria, and they will swarm down upon you and settle into the steep ravines, the crevices of the rocks, on every thorn bush and at every stagnant pool. In that day, the Lord will take his “razor,” the hired king of Assyria from beyond the Euphrates, and he will shave your head, your legs, and also your beard, leaving you ashamed and exposed!
