The next day the great crowd that had come for the Feast heard that Jesus was on his way to Jerusalem. They took palm branches and went out to meet him, shouting, "Hosanna! " "Blessed is he who comes in the name of the Lord!" "Blessed is the King of Israel!" (John 12:12-13 NIV)
This was the first celebration of Palm Sunday. A great crowd, composed mostly of disciples, gathered to glorify Jesus Christ; praising Him as the King of Israel.
