18I lifted up my eyes, and saw, and, behold, four horns. 19I said to the angel who talked with me, What are these? He answered me, These are the horns which have scattered Judah, Israel, and Jerusalem. 20Yahweh showed me four smiths. 21Then said I, What come these to do? He spoke, saying, These are the horns which scattered Judah, so that no man did lift up his head; but these are come to terrify them, to cast down the horns of the nations, which lifted up their horn against the land of Judah to scatter it.
