Zechariah 1:21

Then, so soon as I could propose the question, immediately upon sight of the carpenters, said I, Zechariah, What come these to do? he saw they were men, inquires not who they were, but what was their business and design; perhaps it is fittest for us to rest also in the knowledge of what they are to do, and inquire no further who they were. And he spake; the Lord Christ informed the prophet. These are the horns which have scattered Judah: Christ doth in order to satisfy the inquiry first point to the four horns, of which Malachi 1:18,19, as if he should have said, Look you, there are four horns which have done mischief to Judah. So that no man did lift up his head; kept them so under, none had either strength or courage to lift up the head, and thus these horns proudly and cruelly destroyed my people. But these, these carpenters, or smiths, are emblems of those instruments God will employ in breaking these destroyers. Here are four carpenters to break the four horns. To fray them; to strike a fear into them first; these kingdoms, signified by horns, shall lose their courage. To cast out the horns; then their authority and power shall be cast out easily. The Gentiles; heathen round about Judea. Which lifted up their horn over, have employed their arms and strength against, the land of Judah, the whole kingdom of Judah, God's people, to scatter it, to drive them out of God's inheritance, See Malachi 1:19.
