Palm Sunday is the day we remember the "triumphal entry" of Jesus into Jerusalem, exactly one week before His resurrection. Some 450-500 years earlier, the Prophet Zechariah had prophesied, "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” (Zechariah 9:9). Matthew 21:7-9 records the fulfillment of that prophecy.
