Ephraem the Syrian
I witnessed in the chariot of the first, red steeds—these symbolize the Babylonians, the architects of the initial empire; "and in the chariot of the second, horses of the second"—these represent the Persians, who invaded the territory of Babylon; "and the white men followed them" (Zech. 6:6)—which denote the Macedonians. The Persians and the Macedonians together toppled the Babylonian kingdom and brought about its demise. Such visions were granted to the prophet as a divine revelation to uplift the disheartened people of Judah and to reassure them that they would no longer have to live in fear of the Babylonians.
