Matthew 21:1-7, Mark 11:1-7, Luke 19:29-35.
In Jerusalem, Jesus ordered two disciples to go into the village ahead of him, and said "You will find a colt tied, which never have been ridden. Untie it and bring it to me. If anyone asked why you do it, just say that your Lord needs it.".
They went into the village and they found a colt as Jesus said to them. Jesus rode this donkey from the Mount of Olives into Jerusalem.
Long before Jesus was born, Zachariah the prophet said this would happen, which is in Zechariah 9:9.
