הלכה על במדבר 29:8

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.
