In mounting a colt and riding into Jerusalem, Jesus is deliberately fulfilling the prophecy of Zechariah 9:9: Rejoice greatly, O daughter Zion! Shout aloud, O daughter Jerusalem! Lo, your king comes to you; triumphant and victorious is he, humble and riding on a donkey, on a colt, the foal of a donkey. Jesus is deliberately and provocatively claiming to be the promised king of Israel.
