פירוש על במדבר 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).
