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 ~Zec 9:9

[500 years later...]
The two disciples brought the donkey and the colt to Jesus and threw their garments over the colt, and he sat on it ~Matt 21:6-7

Jesus found a young donkey and rode on it, fulfilling the prophecy ~John 12:14
