"Jesus' Triumphal Entry in Jerusalem on a Donkey
Now when they drew near to Jerusalem and came to Bethphage, to the Mount of Olives, then Jesus sent two disciples, saying to them, "Go into the village in front of you, and immediately you will find a donkey tied, and a colt with her. Untie them and bring them to me. If anyone says anything to you, you shall say, 'The Lord needs them,' and he will send them at once." This took place to fulfill what was spoken by the prophet, saying, "Say to the daughter of Zion, 'Behold, your king is coming to you, humble, and mounted on a donkey, and on a colt, the foal of a beast of burden." ~ Matthew 21:1-5
And Jesus found a young donkey and sat on it, just as it is written, "Fear not, daughter of Zion; behold, your king is coming, sitting on a donkey's colt!" His disciples did not understand these things at first, but when Jesus was glorified, then they remembered that these things had been written about him and had been done to him. ~ John 12:14-16
"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." ~ Zechariah 9:9
