John 12:12-16 ESV
The next day the large crowd that had come to the feast heard that Jesus was coming to Jerusalem. So they took branches of palm trees and went out to meet him, crying out, “Hosanna! Blessed is he who comes in the name of the Lord, even the King of Israel!” 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.
