Zechariah 1:19-21

19And I asked the angel that talked with me, ‘What are these horns?’ Then the angel said to me, ‘These are the strong enemies of my people. They took my people out of Judah, out of Israel and out of Jerusalem.’

20Then the Lord showed me four workers with hammers.

21I said, ‘What are these men coming to do?’ The Lord answered, ‘The horns are the enemies that destroyed Judah. They destroyed Judah and they made the people ashamed. The workers came to frighten and to destroy the enemies because they killed many of my people. The enemies took many of my people out of Judah.’
