Jesus fulfilled Zechariah 9:9 when he rode on a donkey during the triumphal entry: “Rejoice greatly, O daughter of Zion! Shout aloud, O daughter of Jerusalem! Behold, your king is coming to you; righteous and having salvation is he, humble and mounted on a donkey, on a colt, the foal of a donkey.” The king did, in fact, come. And he rode on a colt, the foal of a donkey.
Luke 19 records the triumphal entry in detail. Jesus told two of his disciples to go ahead of him when they were on the Mount of Olives. He said, “Go into the village in front of you, where on entering you will find a colt tied, on which no one has ever yet sat. Untie it and bring it here” (Luke 19:30). They did so. They threw their cloaks on the donkey and set Jesus on it. As he rode along, the crowds threw their cloaks on the road.
“As he was drawing near–already on the way down the Mount of Olives–the whole multitude of his disciples began to rejoice and priase God with a lound voice for all the mighty works that they had seen, saying, ‘Blessed is the King who comes in the name of the Lord! Peace in heaven and glory i the highest!'” (vs. 37-38). As Jesus entered Jerusalem the week before he died, there was great rejoicing over him as the peaceful king. Zechariah was fulfilled before their very eyes.
