telling them, "Go into the village ahead of you. At once you will find a donkey tied there, and a colt with her. Untie them and bring them to Me.
If anyone says anything to you, you should say that the Lord needs them, and immediately he will send them."
This took place so that what was spoken through the prophet might be fulfilled:
Tell Daughter Zion, "See, your King is coming to you, gentle, and mounted on a donkey, even on a colt, the foal of a beast of burden."
References for Matthew 21:5
The disciples went and did just as Jesus directed them.
They brought the donkey and the colt; then they laid their robes on them, and He sat on them.
A very large crowd spread their robes on the road; others were cutting branches from the trees and spreading them on the road.
Then the crowds who went ahead of Him and those who followed kept shouting: Hosanna to the Son of David! Blessed is He who comes in the name of the Lord! Hosanna in the highest heaven!
References for Matthew 21:9
When He entered Jerusalem, the whole city was shaken, saying, "Who is this?"
And the crowds kept saying, "This is the prophet Jesus from Nazareth in Galilee!"
