Isaiah 7:16-20

For before the child shall know to refuse the evil, and choose the good, the land whose two kings thou abhorrest shall be forsaken. Jehovah will bring upon thee, and upon thy people, and upon thy father’s house, days that have not come, from the day that Ephraim departed from Judah—even the king of Assyria. And it shall come to pass in that day, that Jehovah will hiss for the fly that is in the uttermost part of the rivers of Egypt, and for the bee that is in the land of Assyria. And they shall come, and shall rest all of them in the desolate valleys, and in the clefts of the rocks, and upon all thorn-hedges, and upon all pastures. In that day will the Lord shave with a razor that is hired in the parts beyond the River, even with the king of Assyria, the head and the hair of the feet; and it shall also consume the beard.
