Halakhah su Levitico 23:27

To Not Skip In the Torah From One Subject to Another; And The Laws Of The Haftarah. Containing 4 Se'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 he 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.

The commandment of the fast on the tenth day of Tishrei: To fast on the tenth day of Tishrei, and this is called The Day of Atonements (Yom HaKippurim), as it is stated (Leviticus 23:27), "But on the tenth of the month, etc. you shall afflict your souls." The explanation appears is Sifra, Achrei Mot, Chapter 7:3): "[This refers to] affliction that causes a diminishing of the soul. What is this? This is eating and drinking." And so [too,] did they, may their memory be blessed, explain in the Gemara (Yoma 74b). And the tradition also came about it, that it is forbidden for washing, anointing, wearing shoes, and sexual relations. And the language of Sifra, Parshat Achrei Mot, Chapter 8:3 is "From where [do we know] that Yom Kippur is forbidden for washing, anointing, [wearing shoes] and sexual relations? [Hence] we learn to say (Leviticus 23:32), 'A Shabbat of shabbaton'" - meaning that the doubling of Shabbat (rest) indicates resting from these things [as well as] resting from nourishment of the body.

The commandment of the additional sacrifice of Yom Kippur: To sacrifice the additional sacrifice on Yom Kippur, as it is stated (Leviticus 23:27), "But on the tenth of the month, etc. and you shall sacrifice a fire-offering to the Lord." And in the Order of Pinchas, the sacrifice is explained, as it is written there (Numbers 29:8), "And you shall sacrifice a burnt-offering to the Lord, a pleasing smell; one young bull, one ram, seven one-year old sheep, etc." And Rambam, may his memory be blessed, brought this verse that is in Pinchas in his tally (Sefer HaMitzvot LaRambam, Mitzvot Ase 48), whereas I have written the one that is first in the Torah. But it all comes to the same thing.
