Les Nombres 28:16 Halakha : Mishneh Torah, Prayer and the Priestly Blessing & Shulchan Arukh, Orach Chayim

On every festival, and likewise on the Day of Atonement and on all the seven days of Passover, two scrolls of the Law are taken out of the ark. In the first, the sections we have named are read. In the second, the section in the book of Numbers referring to the sacrifice for the day (Numbers 28:16-29:39) is read. The reader of the last reads also the lesson from the Prophets.

Two Torah scrolls are taken out. In the first, five people are called to read (if additional aliyot are added on Yom Tov, see Siman 482). The reading is from Parashat Bo, starting from "משכו" (Draw out your hands) until "מארץ מצרים על צבאותם" (out of the land of Egypt, by their divisions). The maftir (additional reading) is read from the second scroll in Parashat Pinchas, from "ובחדש הראשון" (On the first month). The Haftarah is from Joshua, starting with "בעת ההיא" (At that time). The Mussaf (additional) prayer is then recited, and from this point forward, rain is no longer mentioned (see Siman 114, Section 3). Likewise, from this point on, one stops requesting rain in the Blessing of the Years. Gloss: It is customary on every Yom Tov, in the Mussaf prayer, to recite the verses of the additional offerings of the day after saying "Through Moses, Your servant, as it is stated...".
