L’Éternel parla ainsi à Moïse:

Kitzur Shulchan Arukh

Preface:
As we look into a Seifer Torah we become aware of gaps and spaces in the text. This, as many of the laws and traditions concerning the writing of Sifrei Torah, has been handed down to us from generation to generation, originating from the giving of the Torah at Mt. Sinai. Each of these text-breaks denotes the completion of a chapter. (This should not be confused with the numbered chapters and verses that are found in the printed Scriptures, for these are attributed to non-Jewish sources).41The notations … שֵׁנִי, שְׁלִישִׁי, רְבִיעִי do not constitute halachic parshios.
There are two kinds of text-breaks: 1) פְּתוּחָה pesuchah—"open" i. e. the text ends in mid-line and the remainder of the line is left open with the text resuming at the beginning of the next line. 2) סְתוּמָה sesumah —"closed" i. e. the text ends in mid-line and after the gap, the text resumes on the same line, in effect "closing the line."
Paragraph 20 concerns precautions taken to avoid the impression that less than three verses may ever be read for any one oleh.
The one who reads the Torah must not conclude [his reading] at a place from where there will not remain a minimum of three verses,43So that anyone who might leave the synagogue just then, not leave with the impression that the next reading would contain only two verses. from there until the end of that parshah,42See preface to this paragraph. that is a pesuchah42See preface to this paragraph. or a sesumah. If the oleh had already recited the last berachah after [the reader] completed [the reading] with less than three verses left to the end of that parshah, then the following reading need not begin with the preceding verse,44It is too late to correct any false impressions. but should start where the previous one left off, and continue to read with him at least three more verses in the following parshah. If a parshah only has two verses, it is permitted to end there. If there is a parshah-break in mid-verse, as there is in the beginning of Parshas Pinchos,45Numbers 25:19. the reading may end even at the very next verse.46Because no one could possibly think that one verse was read for an oleh.

Sefer HaChinukh

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, Positive Commandments 48), whereas I have written the one that is first in the Torah. But it all comes to the same thing.

Shulchan Arukh, Orach Chayim

2. We take out two Torah scrolls. In the first one, we read five portions from "God attended Sarah" [Genesis 21:1] until "After these things" [Genesis 22:1]. If it is Shabbat, we read seven portions [from this selection]. The maftir reads from the second scroll from Pinchas, "In the seventh month..." [Numbers 29:1] and for the haftarah, "There was a man from Ramatayim" [1 Samuel 1:1] until "He will bring triumph to His annointed one" [1 Samuel 2:10]. Rem"a: Some places have the custom of calling up the shofar blower for one of the five aliyot to the Torah (Kol Bo).
