A pilgrim from the Galilee

Scene 1 of 7
Leaving home
The Torah asks every household to 'appear before the Lord' three times a year. Your village sets out days before the festival, carrying food for the road. Someone starts a psalm, and the rest join in.
Scene 2 of 7
The first sight
On the last ridge, the walls of Jerusalem appear, and above them the pale tower of the Sanctuary. Someone recites: 'I rejoiced when they said unto me: Let us go unto the house of the Lord. Our feet are standing within thy gates, O Jerusalem.'
Scene 3 of 7 · The Temple Mount
Preparing
You immerse in a mikveh before going up. Entering the Mount, you turn to the right with the crowd and circle; a woman walking the other way is a mourner, and people say to her, 'May He who dwells in this house comfort you.'
Scene 4 of 7 · The Azarah (inner courtyard)
The three groups
On the afternoon of the fourteenth, your group enters the Azarah with its lamb. The doors close. Trumpets sound. Priests stand in rows holding basins of silver and gold, passing them hand to hand toward the altar.
Scene 5 of 7 · The Fifteen Steps
Hallel
The Levites sing Hallel while your group is inside. The Mishnah notes the third group was so small that the Levites never reached the start of Psalm 116.
Scene 6 of 7
The meal
That night, in a borrowed room in Jerusalem, your group eats the Pesach offering with matzah and bitter herbs and tells the story of the Exodus. The same order is still kept at every Seder.
Scene 7 of 7
Home
On the road north, the psalm starts again. The song you sang going up is the song you carry home.
