If Yom Tov of Rosh Hashanah fell on Shabbat, they would blow the shofar in the Temple but not in the country. After the destruction of the Temple, Rabban Yohanan ben Zakai decreed that it should be blown [on Shabbat] in every place where there was a court. Rabbi Eliezer said: Rabban Yohanan ben Zakai decreed for Yavneh only. They said to him: both Yavneh and any place where there is a court.

There was another way in which Jerusalem was greater than Yavneh, that in every city which could see [Jerusalem] and hear and was near and could get to Jerusalem, they used to blow [on Shabbat], whereas in Yavneh they used to blow in the court only.

In earlier times the lulav was taken for seven days in the Temple, and in the provinces for one day only. When the temple was destroyed, Rabbi Yohanan ben Zakkai decreed that the lulav should be taken in the provinces for seven days in memory of the Temple, [He also decreed] that on the whole of the day of waving it be forbidden [to eat the new produce].

Originally they used to accept testimony with regard to the new moon during the whole day. On one occasion the witnesses were late in arriving, and the Levites went wrong in the daily hymn. They therefore decreed that testimony should be accepted only until the afternoon [sacrifice]. If witnesses came after the afternoon sacrifice that day should be kept as holy and also the next day. After the destruction of the temple Rabban Yohanan ben Zakkai decreed that testimony with regard to the new moon should be received during the whole day. Rabbi Joshua ben Korha said: this further did Rabbi Yohanan ben Zakkai decree, that not matter where the head of the court might be, the witnesses should have to go only to the place of the assembly.

The order of blessings [in the Musaf Amidah of Rosh Hashanah]:He says “patriarchs”, “powers” and the “sanctification of the name” and includes the kingship verses with them and does not blow [the shofar]. The sanctification of the day and blows [the shofar], the remembrance-verses and blows [the shofar], and the shofar-verses and blows [the shofar]. Then he says the blessing of the Temple service and “thanksgiving” and the blessing of the priests, the words of Rabbi Yohanan ben Nuri. Rabbi Akiva said to him: if he does not blow the shofar for the kingship-verses, why should he say them? Rather he says: “patriarchs”, “powers” and the “sanctification of the name” and includes the kingship verse with the sanctification of the day and blows the shofar, then he says the remembrance-verses and blows, and the shofar-verses and blows. Then he says the Temple service and “thanksgiving” and the blessing of the priest.

The one who passes before the ark on the festival of Rosh Hashanah: the second one blows the shofar. On days when Hallel is said, the first one recites the Hallel.

[For the sake of] the shofar of Rosh Hashanah one is not allowed to go past the [Shabbat] border, nor remove a pile of rocks, nor climb a tree, nor ride on an animal, nor swim on the water. One may not cut it, neither with an instrument forbidden because of shevut, nor with an instrument forbidden by a negative commandment. But if he wants to pour wine or water into it he may do so. They need not prevent children from blowing the shofar [on Rosh Hashanah]; on the contrary, they may help them until they learn how to blow. One who is just practicing has not fulfilled his obligation, and the one hears [the blast made] by another when practicing has not fulfilled his obligation.

The order of the blasts: three sets of three each. The length of a teki’ah is equal to three teru'ahs, and the length of a teru'ah is equal to three yevavot. If one prolonged the first teki'ah so that it went directly into the second, it counts only as one. One who has blessed [recited the Amidah] and then a shofar is given to him, he sounds a teki'ah teru'ah teki'ah three times. Just as the shaliah tzibbur is obligated, so every single individual is obligated. Rabban Gamaliel says: the shaliah tzibbur (communal prayer leader) causes the whole congregation to fulfill their obligation.
