Йешайау 12:3 Ссылки в Мишне: Mishnah Sukkah

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.

The flute was for five or six days. This refers to the flute at the Bet Hashoevah [the place of the water-drawing] which does not override Shabbat or the festival day. They said: he who has not seen the Simchat Bet Hashoevah has never seen rejoicing in his life.
