(Bamidbar 28:11) "And in the beginnings of your months, you shall offer a burnt-offering to the L-rd": What is the intent of this? From (Ibid. 4) "The one lamb shall you offer in the morning," I understand the beginning of the month (Rosh Chodesh) also to be included; therefore, Scripture removes it from the general category for greater stringency — the mussafim (of Rosh Chodesh). (But why is a special verse needed for the mussafim of Rosh Chodesh?)
Let it be derived from (the mussafim of) Sabbath? (In that case I would say:) Just as (the mussafim of) Sabbath are two lambs, so, those of Rosh Chodesh; it is, therefore, written "And in the beginning of your months, you shall offer a burnt-offering to the L-rd, etc." — Scripture adduces a different numeration. R. Elazar b. R. Tzaddok says: There was a hin (a liquid measure) in the Temple, with markings: Thus far (the libation) for a bullock; thus far for a ram; thus far for a sheep.
R. Yishmael says: There was no hin, but an additional measure of a log and a half in which was apportioned the high-priest's meal-offering, a log and a half in the evening, a log and a half in the morning.
