Christ Entering Jerusalem is the final visit to the city, described by all four evangelists: Matthew 21:1-11; Mark 11:1-10; Luke 19:29-38; John 12:12-15.
It happened several days before the Passover festival, and the crowds of pilgrims who had come for the festival went out to meet him "with palm branches in their hands, shouting , 'Hosanna! blessed is the king of Israel!" (John 12:13).
"Crowds of people carpeted the road with their cloaks, and some cut branches from the trees to spread
in his path." (Matthew 21:8). "
"Jesus found a donkey and mounted it, in accordance with the words of scripture: 'Fear no more, daughter of Zion; see, your king is coming, mounted on a donkey's colt.' At the time his disciples did not understand this, but after Jesus had been glorified they remembered that this had been written about him, and that it had happened to him." (John 12:14-16).
When he entered Jerusalem the whole city went wild with excitement. 'Who is this?' people asked, and the crowds replied, 'This is the prophet Jesus, from Nazareth in Galilee.' (Matthew 21:10-11)
