The next day the great crowd that had come to the festival heard that Jesus was coming to Jerusalem. So they took branches of palm trees and went out to meet him, shouting, “Hosanna! Blessed is the one who comes in the name of the Lord— the King of Israel!” [John 12:12-13]
The Lord is God, and he has given us light. Bind the festal procession with branches, up to the horns of the altar. You are my God, and I will give thanks to you; you are my God, I will extol you. O give thanks to the Lord, for he is good, for his steadfast love endures forever. [Psalm 118:27-29]
