The Torah in Parashat Pinhas (Bamidbar 28:9) commands offering a special Musaf sacrifice each week on Shabbat, consisting of two sheep. The Sefer Ha’hinuch explains that this Misva is aimed at drawing our attention to the significance of Shabbat, as the day which commemorates, and actually testifies to, G-d’s creation of the world in six days. This Musaf offering, as mentioned, consists of just two sheep, making it the smallest of all the Musaf sacrifices. The Midrash explains that G-d commanded offering two sheep because of the theme of doubling which features prominently on Shabbat. Just as we have two loaves of bread at the table, we offer a sacrifice that is double the daily Tamid sacrifice, which consists of just one sheep. The next Misva listed by the Sefer Ha’hinuch is the Musaf sacrifice offered each month on Rosh Hodesh. The Torah (Bamidbar 28:11-15) requires offering for this sacrifice two bulls, one ram, seven sheep, and a goat as a sin-offering. The Sefer Ha’hinuch explains that a special sacrifice is required on Rosh Hodesh because the new moon – the advent of which is when Rosh Hodesh occurs – affects many aspects of nature. It is well known that the moon’s size affects the tides, and thus sailors would schedule their voyages around the lunar cycle. But in addition, as the Sefer Ha’hinuch writes, the lunar cycle affects the quality of trees, such that those who cut trees for wood would refrain from doing so around the time of the new moon. People also made a point not to perform bloodletting around this time. In fact, it was believed that soaking flax around the time of the new moon would cause the flax to spoil. In light of this effect on the natural world, the Sefer Ha’hinuch writes, the Torah requires offering a sacrifice on Rosh Hodesh to remind us that everything that happens in the world is directly governed and controlled by G-d, and nothing occurs on its own. If Rosh Hodesh falls on Shabbat, then both Musaf offerings are brought, but the Leviyim would sing the song for Rosh Hodesh, instead of the song for Shabbat, to publicize the observance of Rosh Hodesh. The 404 th Biblical command listed by the Sefer Ha’hinuch is the Musaf sacrifice required on Shabuot (Bamidbar 28:27). A unique feature of this Musaf is the Torah’s formulation in commanding the offering of a goat as a sin-offering. Whenever the Torah commands offering a goat as a sin-offering, it makes a point of stating that the goat is brought as a “Hatat,” to atone for sin; in the context of Shabuot, however, the Torah simply states that we must offer a goat, without mentioning the word “Hatat.” The Talmud Yerushalmi (Masechet Rosh Hashanah) explains that Shabuot celebrates our receiving the Torah, and G-d tells us that if we wholeheartedly commit ourselves to the Torah, then we are considered to never have sinned in our lives. Our genuine devotion to Torah learning has the effect of purging our misdeeds, as though they never occurred, and so in the context of Shabuot, the day which celebrates our renewed commitment to Torah, the word “Hatat” is omitted, alluding to the erasure of our sins in the merit of our commitment to the Torah.
