[The rituals of] the lulav and the aravah are for six or seven [days]; The Hallel and the rejoicing are for eight [days]; The sukkah and the water libation are for seven [days]; The flute is for five or six [days].

“The lulav for seven.” How so? If the first day of the festival fell on Shabbat, the lulav [is taken for] seven days; on any other day, [it is taken] for six.

“The aravah seven days.” How is this? If the seventh day of [the ritual of] the aravah fell on Shabbat, [it lasts] seven days; if it fell on any other day, [it lasts only] six.

The mitzvah of the aravah how was it [performed]?There was a place below Jerusalem called Moza. They went down there and gathered tall branches of aravot and then they came and stood them up at the sides of the altar, and their tops were bent over the altar. They then sounded a teki’ah [long blast], a teru’ah [staccato blast] and again a teki’ah. Every day they went round the altar once, saying, “O Lord, save us, O Lord, make us prosper” (Psalms 118:. Rabbi Judah says: “Ani vaho, save us.” On that day they went round the altar seven times. When they departed, what did they say? “O altar, beauty is to you! O altar, beauty is to you!” Rabbi Eliezer said: [they would say,] “To the Lord and to you, O altar, to the Lord and to you, O altar.”

As was its performance on a weekday, so was its performance on Shabbat, except that they would gather them on the eve of Shabbat and place them in golden basins so that they would not become wilted. Rabbi Yohanan ben Beroka says: they used to bring palm branches and they would beat them on the ground at the sides of the altar, and that day was called “[the day of] the beating of the palm branches.”

Immediately after beating the willows (or palm branches) the children undo their lulavs and eat their etrogim.

The Hallel and rejoicing are on all eight days: How is this so? This teaches that one is obligated for the Hallel, for rejoicing and for honoring the festival on the last day, just as he is on all the other days of the festival. The sukkah is for seven days. How so? Once he finished eating [his meal on the seventh day], he should not untie his sukkah, but he removes its contents from the time of minhah and onwards in honor of the last day of the festival.

How was the water libation [performed]? A golden flask holding three logs was filled from the Shiloah. When they arrived at the water gate, they sounded a teki'ah [long blast], a teru'ah [a staccato note] and again a teki'ah. [The priest then] went up the ascent [of the altar] and turned to his left where there were two silver bowls. Rabbi Judah says: they were of plaster [but they looked silver] because their surfaces were darkened from the wine. They had each a hole like a slender snout, one being wide and the other narrow so that both emptied at the same time. The one on the west was for water and the one on the east for wine. If he poured the flask of water into the bowl for wine, or that of wine into that for water, he has fulfilled his obligation. Rabbi Judah says: with one log he performed the ceremony of the water-libation all eight days. To [the priest] who performed the libation they used to say, “Raise your hand”, for one time, a certain man poured out the water over his feet, and all the people pelted him with their etrogs.

As it was performed on weekdays, so was it was performed on Shabbat, save that on the eve of Shabbat he would fill a non-sanctified golden barrel from the Shiloah, and place it in the chamber. If it was poured away or uncovered, he would refill it from the laver, for wine or water which has become uncovered is invalid for the altar.
