Isaiah 7:16-20
16 But 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.
17 The 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.”
18 In that day the Lord will whistle for flies from the distant streams of Egypt and for bees from the land of Assyria.
19 They 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.
20 In that day the Lord will use a razor hired from beyond the River—the king of Assyria—to shave your head and the hair of your legs, and to take off your beards also.
