Zechariah 1:18-21

Then I looked up and saw four animal horns. “What are these?” I asked the angel who was talking with me. He replied, “These horns represent the nations that scattered Judah, Israel, and Jerusalem.” Then the LORD showed me four blacksmiths. “What are these men coming to do?” I asked. The angel replied, “These four horns—these nations—scattered and humbled Judah. Now these blacksmiths have come to terrify those nations and throw them down and destroy them.”
