Isaiah 7:16-20

For before the boy will know enough to refuse evil and choose good, the land whose two kings you dread will be forsaken. The LORD will bring on you, on your people, and on your father’s house such days as have never come since the day that Ephraim separated from Judah, the king of Assyria.” In that day the LORD will whistle for the fly that is in the remotest part of the rivers of Egypt and for the bee that is in the land of Assyria. They will all come and settle on the steep ravines, on the ledges of the cliffs, on all the thorn bushes and on all the watering places. In that day the Lord will shave with a razor, hired from regions beyond the Euphrates (that is, with the king of Assyria), the head and the hair of the legs; and it will also remove the beard.
