Mark 11:9
Those who went ahead and those who followed shouted, Hosanna! Blessed is he who comes in the name of the Lord — Hosanna is the Hebrew hoshia-na (save now) from Psalm 118:25, the great Hallel psalm sung at major festivals. Blessed is he who comes in the name of the Lord is Psalm 118:26 — the greeting for the one who arrives at the temple in the name of the Lord. The crowd is greeting Jesus with the language of the Passover psalm, using the pilgrim's greeting for the arriving king.
