In this chapter, after the introduction (Zac 1:1), we have, I. An awakening call to a sinful people to repent of their sins and return to God (Zac 1:2-6). II. Great encouragement given to hope for mercy. 1. By the vision of the horses (Zac 1:7-11). 2. By the prayer of the angel for Jerusalem, and the answer to that prayer (Zac 1:12-17). 3. By the vision of the four carpenters that were employed to cut off the four horns with which Judah and Jerusalem were scattered (Zac 1:18-21).
