Isaiah 7:16-20

16for before the boy knows enough to reject the wrong and choose the right, the land of the two kings you dread will be laid waste. 17The Lord will bring on you and on your people and on the house of your father a time unlike any since Ephraim broke away from Judah—he will bring the king of Assyria.” 18In that day the Lord will whistle for flies from the Nile delta in Egypt and for bees from the land of Assyria. 19They will all come and settle in the steep ravines and in the crevices in the rocks, on all the thornbushes and at all the water holes. 20In that day the Lord will use a razor hired from beyond the Euphrates River—the king of Assyria—to shave your heads and private parts, and to cut off your beards also.
