There are to be no less than twenty-one tekioth in the Temple, and no more than forty-eight. Every day there were twenty-one tekioth in the Temple: three at the opening of the gates [When the gates of the azarah were opened, they blew tekiah, teruah, tekiah (which are considered "three tekioth")], nine at the morning tamid [When they poured the tamid libations, the Levites sang. They paused three times, and for each pause the Cohanim blew tekiah, teruah, tekiah — hence, nine tekioth.], and nine at the afternoon tamid. At the mussafin, they would add another nine, and on Sabbath eve, they would add another six: three, to (signal) the people to stop working: [the first, for the people in the fields; the second, for the removal of shutters and closing of the shops; the third, for the removal (of food from the fire), storing warm dishes, and lighting the Sabbath candles], and three to separate the holy from the profane. [After the first tekioth, he would wait the amount of time it takes to roast a small fish and blow: tekiah, teruah, tekiah — these last three tekioth to announce the arrival of the Sabbath.] On Sabbath eve in the midst of the festival (Succoth), there were forty-eight (tekioth): three at the opening of the gates [of the azarah, as on all days], three at the upper gate, [as stated above (5:4): "Two priests would stand in the upper gate … When the rooster crowed, they would blow: tekiah, teruah, tekiah"], three at the lower gate, [as we learned above: "When they reached the azarah, they would blow: tekiah, teruah, tekiah, and they would draw out the tekiah until they reached the lower gate." As it was taught: "They blew as they went until they reached the lower gate" — hence: "three at the lower gate." (The three of the tenth ascent are not reckoned, this tanna holding with R. Eliezer b. Yaakov, who says that they did not blow at the tenth ascent.)], three at the filling of the water [After they drew it and came to the azarah through the Water Gate, they blew: tekiah, teruah, tekiah.], three "atop the altar" [(Ibid. 4:5): "They would stand them on the sides of the altar … They would blow: tekiah, teruah, tekiah." Our tanna does not adduce here the instance of Pesach eve falling out on a Sabbath. (For the Pesach offering is slaughtered in three groups and there were many tekioth there.) (Still, he does not adduce it) for it is not that common for Pesach eve to fall on a Sabbath. As to our learning: "There are to be no more than forty-eight (tekioth)" — not necessarily. For when Pesach eve falls out on a Sabbath, sometimes there are as many as fifty-seven tekioth.], nine at the morning tamid, nine at the afternoon tamid, nine at the mussafin, three to (signal) the people to stop working, and three to separate the holy from the profane.
