It’s more than just a random rule. to Vayikra Rabbah 27 and see what wisdom we can uncover.
"A bull, a sheep, or a goat, when it is born, shall be seven days under its mother." Why those seven days? The text explains that this period allows for careful observation. Imagine the newborn animal being examined for any signs of injury, perhaps from being gored by its mother. If any blemish is found, it's deemed unfit for offering. It has to be whole and perfect.
This idea connects to another interesting point about childbirth. The Mishna Nidda (5:1) discusses a birth by caesarean section. According to the first tanna, a child born this way isn't considered to have gone through a normal birth process, and the mother doesn't observe the usual days of impurity and purity, nor is she obligated to bring the standard offering. Rabbi Shimon disagrees, viewing it as a natural birth. So, why does this matter? Well, the verse specifies an animal that is "born" – implying a natural birth. A natural birth carries the risk of injury, hence the seven-day waiting period to ensure there are no blemishes before it’s offered.
But wait, there's more! Rabbi Yehoshua of Sikhnin, quoting Rabbi Levi, offers a beautiful analogy. Imagine a king entering a province and declaring that no one can have an audience with him until they’ve first had an audience with the queen. Similarly, God says, "Do not bring an offering before Me until Shabbat will pass for it." Why? Because there are no seven days without Shabbat, and there is no circumcision without Shabbat. It's all interconnected.
And that leads to the eighth day. "From the eighth day on, it shall be accepted" (Leviticus 22:27). Rabbi Yitzchak points out the parallel between humans and animals. With humans, on the eighth day, the flesh of the foreskin is circumcised (Leviticus 12:3). With animals, on the eighth day, they become acceptable as offerings.
But there's a crucial condition. The offering must be brought willingly, with a good heart. If it's done by force, against your will, it's not truly an offering to God. It’s just a "fire offering to the Lord" (Leviticus 22:27). The term "fire offering" or isheh in Hebrew, suggests that the person views it as a wasteful burning of an animal. The Torah says, “Command the children of Israel, and say to them: My offering, My food, for My fires” (Numbers 28:2). If you bring an offering willingly, it’s “My offering.” But if it’s by force, it’s just fuel "to My fires" – and not truly connected to the Name of God.
So, what's the big takeaway here? It's not just about following rules. It’s about intention, about willingness, about the heart you bring to the act. The seven days of waiting, the eighth day of acceptance – they all emphasize the importance of preparation, of ensuring that what we offer, whether it's an animal sacrifice or our own service, is given freely and with a pure heart. Is it truly korbani - "My offering" - or just isheh - a fire? It's a question worth pondering.
