Halakhah sa Levitico 23:23: The Sabbath Epistle & Shulchan Arukh, Orach Chayim

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).

To Not Skip In the Torah From One Subject to Another; And The Laws Of The Haftarah. Containing 4 S'ifim:
We skip in the Prophets, but we do not skip in the Torah from one section to another section. And this is in regards to two subjects where we are worried that perhaps the mind of the listeners will be confused, but with one subject, for example “Acharei Mot” [Lev. 16:1] and “Akh Be-asor” [Lev. 23:27] that the High Priest reads on Yom Kippur, we skip. And this is a long as one does not read by heart, as it is forbidden to recite even one word not from writing. And in the Prophets, we skip even with two subjects. And this is if one does not delay when skipping into [another] matter so that the congregation does not [have to] stand in silence [waiting]. And this is in regards to [reading] within one [book of the] Prophets, but from one [book of the Prophets] to another [book of the Prophets], we do not skip. And within the Trei Asar [i.e. Twelve Minor Prophets], we skip from prophet to prophet, as long as one does not skip from the end of the book to its beginning.
