Comentario sobre Números 28:19

פרים BULLOCKS — in allusion to Abraham, as it is said, (Genesis 18:7) “And unto the herd (the bullock) Abraham ran”,

תמימים יהיו לכם, “they shall be free from blemish, for you.” If animals used as communal offerings on the Sabbaths or festivals should have a blemish disqualifying them as offerings, slaughtering such animals on the Sabbath or festival would be a grave sin. It would even be forbidden to remove the skins of such animals on either the Sabbath or the festival. This is why the prophet Ezekiel, Ezekiel 22,8 stated: קדשי בזית ואת שבתותי חללת, “you have despised My holy things, and you have profaned My Sabbaths.” This is also why no mention is made of the animals for the offerings on New Moon having to be free from blemish. It is clear that all animals for offerings must be free from blemishes on any day of the week, but if these animals are offered on a day when certain work must not be performed, if such an animal is nonetheless being offered, the person doing so has committed an additional sin, that of profaning the holiness of the day.

אילים RAMS — in allusion to the ram of Isaac (Genesis 22:13).

כבשים LAMBS — in allusion to Jacob, as it is said, (Genesis 30:40) “And the lambs did Jacob set aside”. I saw this in the work of R. Moses the Preacher (see Rashi on Numbers 7:21).

That is that He commanded to offer a sacrifice on all seven days of Pesach in addition to the daily offering. And that is His, may He be exalted, saying, "Seven days shall you offer a fire-offering to the Lord" (Leviticus 23:36). (See Parashat Emor; Mishneh Torah, Daily Offerings and Additional Offerings 7.)
