Zechariah 6:1

Four chariots. The four great empires of the Chaldeans, Persians, Greeks, and Romans; or, perhaps, by the fourth chariot are represented the kings of Egypt and of Asia, the descendants of Ptolemeus and Seleucus. (Challoner) (See Daniel ii.) (Worthington) --- The chariots seem to represent the same thing as the four horns, (chap. i. 18.) namely, the punishment of the four empires. The angel says nothing of the first chariot, as the Chaldeans, who overthrew the Assyrians, were now devoid of power. --- Brass, or hard; signifying that the chariots were designed to bruise nations. (Calmet) --- Empires depend on the decrees of God. (Menochius) --- The two mountains may denote the passes of Cilicia, through which the conquerors must pass from Egypt and Syria to Babylon. (Tournemine)
