Chapter 78 – Torah Reading on Sabbath and Festivals
78.1) If more than seven persons are called up to the Torah on the Sabbath, a kohen or Levi may read the last portion of the maftir (the last person called up to the Torah on Shabbat and holiday morning).
78.2) If the portion was allotted to a Y’Israel, and a kohen (priest) or Levi is erroneously called up, someone else must be called up.)
78.3) When two sections of Scripture are called up on the Sabbath and read, they are merged into one with the reading of the fourth portion.
78.4) Do not interrupt the reading of the curses.
78.5) Roll up the Scroll between the reading for one person and another; you need not cover the Scroll.
78.6) Recite the maftir, but not the kiddush, when in error someone reads for the sixth person up to the end of the Sidra.
78.7) When three Scrolls are required and you have only two at the reading, do not roll to the portion of the second Scroll that is to be read.
78.8) If a defect is found in the Scroll for the reading of the maftir, follow the rules that govern the rules of defects in Scrolls, in chapter 24.
78.9) Do not take out another Scroll when you find a defect while reading it for the maftir.
78.10) If you take out two Scrolls for the reading of the maftir and find a defect, do not read out of the second Scroll.
78.11) There are rules for the order of precedence for the reading of the Torah. See the source for that list.
