Zechariah 1:18-21 - Zechariah's Second Vision
18 Then I lifted up my eyes, and saw, and behold four horns. 19 And I said unto the angel that talked with me, What are these? And he answered me, These are the horns which have scattered Judah, Israel, and Jerusalem.
20 And the LORD showed me four craftsmen. 21 Then said I, What are these coming to do? And he spoke, saying, These are the horns which have scattered Judah, so that no man did lift up his head: but these have come to terrify them, to cast out the horns of the nations, who lifted up their horn over the land of Judah to scatter it.
