On Rosh Chodesh and on Chol HaMoed, four [people] read [the Torah]; we may not decrease them nor add to them; and we do not conclude [the reading with a section] from the Prophets. The one who commences and the one who concludes [the reading of] the Torah [respectively] recite the blessings [said] before it and after it.  This is the general rule: [On] any day on which there is a Musaf but which is not a festival, four [people] read [the Torah]. On festivals, five [people read]; on Yom Kippur, six [people read]; and on the Sabbath, seven [people read]; we may not decrease them but we may increase them; and we conclude [the reading with a section] from the Prophets. The one who commences and the one who concludes [the reading of] the Torah [respectively] recite the blessings [said] before it and after it.
