Mishnah Rosh Hashanah
All shofars may be used except for that of a cow, because it is a keren. Rabbi Yose said: Are not all shofars called keren as it says, “When they make a long blast with the ram’s keren [horn]?” (Joshua 6:5).
Mishnah Rosh Hashanah
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.
