You can probably visualize it from your childhood religious teachings. Jesus on a donkey, people waving palm fronds. Do you know the whole story?
Jesus was on his way to Jerusalem, knowing full well that this trip would end in his sacrificial death for the sin of humanity.
He sent two disciples ahead to the village of Bethphage, about a mile away from the city at the foot of the Mount of Olives. He told them to look for a donkey tied by a house, with its unbroken colt next to it. Jesus instructed the disciples to tell the owners of the animal that “The Lord has need of it.” (Luke 19:31, ESV)
The men found the donkey, brought it and its colt to Jesus, and placed their cloaks on the colt. Jesus sat on the young donkey and slowly, humbly, made his triumphal entry into Jerusalem. In his path, people threw their cloaks on the ground and put palm branches on the road before him. Others waved palm branches in the air.
Large Passover crowds surrounded Jesus, shouting “Hosanna to the Son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest!” (Matthew 21:9, ESV)
By that time the commotion was spreading through the entire city. Many of the Galilean disciples had earlier seen Jesus raise Lazarus from the dead. Undoubtedly they were spreading the news of that astonishing miracle.
The Pharisees, who were jealous of Jesus and afraid of the Romans, said: “‘Teacher, rebuke your disciples.’ He answered, ‘I tell you, if these were silent, the very stones would cry out.'” (Luke 19:39-40, ESV)
