Halakhah for Numbers 29:1

We also find written⁸³ Ibn Ezra now proceeds to show that for some matters the year begins with the month of Tishre. Here he seems to be countering the Karites, who did not accept the first of Tishre as Rosh haShana. The Karites argued that there is no Scriptural basis for the first of Tishre being anything other than a day when work is forbidden (Leviticus 23:23–25) and special sacrifices are offered (Numbers 29: 1–5). The Karites began the year for all religious matters with the first of Nisan. with regard to Tabernacles “at the turn of the year” (Exodus 34:22), and also “at the departure of the year” (ibid. 23:16). Now the same day when one year ends a new year begins. We also find that God instructed us in a law of Haqhel, when the entire Torah is read during the holiday of Tabernacles of a Sabbatical year (Deuteronomy 31:10–13). There it is written “in order that they may learn” (ibid. 31:12). It is not likely that this took place after half a year.⁸⁴ Thus, Haqhel certainly took place at the beginning of a Sabbatical year, indicating that a Sabbatical year began around the time of Tabernacles. Do not be perplexed by the word “At an end (miqqez) of seven years” (ibid. 31:10),⁸⁵ The verse concerning Haqhel reads: “At the end of seven years, in the time of the Sabbatical year, on the holiday of Tabernacles,” which seems to indicate that the celebration of Haqhel took place at the conclusion of the Sabbatical year and the beginning of the eighth year. for we similarly find “At an end (miqqez) of seven years you shall send forth, each man his brother” (Jeremiah 34:14).⁸⁶ We know that servants were set free after six years (Exodus 21:2). Thus “miqqez” must here refer to the beginning of the seventh year. Similarly for Haqhel, the word “miqqez” means “beginning” rather than “end.” For each thing has two edges, a front edge and a back edge. The Sabbatical year began with Tishre,⁸⁷ Here Ibn Ezra refutes the Karites who began the Sabbatical year with Nisan. (See Ibn Ezra’s commentary to Leviticus 25:20.) which is the seventh month, since then the half year of planting began. Thus it states regarding the Sabbatical year “do not plant” (Leviticus 25:4), and “You shall plant on the eighth year” (ibid. 25:22).

The commandment of blowing the trumpets in the Temple and in war: To blow trumpets in the Temple each day as every sacrifice is offered, and also at a time of troubles, as it is stated (Number 10:9), "When you come to war, etc." and it is written after it also (Number 10:10), "And on your joyous occasions, and your fixed festivals and new moon days, you shall blow the trumpets over your burnt-offerings and over the sacrifices of your peace-offerings, etc." And even though the verse warns about a joyous occasion, a fixed festival and a new moon day, this is not precise. As they would blow with the trumpets over the sacrifice every day in the Temple. And so is it explained in Rosh HaShannah 29a: "Everyone is obligated in the blowing of the shofar - priests, Levites, and Israelites." And the Talmud wonders about this in the Gemara, "Is this not obvious? [For] if they are not obligated, who would be obligated?" And it responds to it, "It was necessary [to say] priests, for it may enter your mind to say, 'Since it is written (Numbers 29:1), "It is a day of blowing, etc.," [you might have said that with regard to one who is obligated to sound only one day, he is obligated to sound the shofar on Rosh HaShanah.] But these priests, since they are [obligated] all year long, as it is written (Numbers 10:10), "you shall blow the trumpets over your burnt-offerings and over the sacrifices of your peace-offerings, etc." [you might say that they are not obligated].'" The Talmud then asks, "Are they similar? There it is a trumpet and here it is a shofar!" Nevertheless, we learned [from this] that throughout the whole year - meaning to say on each and every day - there were trumpets in the Temple. And they said in Tractate Arakhin 13a that we do not reduce to less than twenty-one blasts in the Temple and we do not increase to over forty-eight.

The commandment of shofar (horn) on Rosh Hashanah: That we were commanded to hear the sound of the shofar on the first day of Tishrei, which is Rosh Hashanah - and as we learn in Tractate Rosh Hashanah 2a, "On the first of Tishrei is the beginning of the year (rosh hashanah) for [calculating] years" - as it is stated (Numbers 29:1), "a day of blowing shall it be for you." And even though there is no mention of [how] this blast [should be done], if with a shofar, or with cymbals, or with any other musical instrument; they, may their memory be blessed, learned from [the oral tradition] (Rosh Hashanah 33b) that it is with a shofar, as we found with regard to the jubilee year, about which it states (Leviticus 25:9), "shofar."
