Zechariah portrayed the Messiah so often that he falls second only to the prophet Isaiah in the number of Messianic prophecies mentioned. These Messianic prophecies are so clear that Luther called Zechariah, “One of the most comforting of all the prophets.” Our summary verse is from Zechariah 9:9: “Rejoice greatly, O daughter of Zion! Shout, O daughter of Jerusalem! Behold, your King is coming to you; He is just and having salvation, Lowly and riding on a donkey, A colt, the foal of a donkey.” – (NKJV)
