Our journey begins in Sifrei Devarim, a collection of legal interpretations on the Book of Deuteronomy. We're looking at section 104, a passage attributed to R. Yossi Haglili, a sage from the early generations of the Tannaim (the rabbinic authorities whose views are recorded in the Mishnah).

He starts with two seemingly separate prohibitions: “You shall not eat any neveilah (carcass)” (Deuteronomy 14:21), and “You shall not cook a kid in the milk of its mother” (Exodus 23:19, 34:26, Deuteronomy 14:21). What’s the connection?

R. Yossi Haglili points out that what's forbidden as neveilah – an animal that died of natural causes or was improperly slaughtered – is also forbidden to cook in milk. Okay, makes sense so far. But then he throws us a curveball.

What about birds? A bird is forbidden as neveilah. So, could we think it’s forbidden to cook a bird in milk, too? That’s where the Torah, in its infinite wisdom, throws in a little clarification: "in its mother's milk." This phrase, R. Yossi argues, is there specifically to exclude birds. Why? Because birds don't produce milk!

So, the initial interpretation suggests that the prohibition of cooking meat in milk applies specifically to animals that have a mother that produces milk. It’s a subtle but important distinction. (And yes, this is part of the foundation for why observant Jews don't mix meat and dairy.)

But wait, there’s more!

The Torah actually repeats the phrase "You shall not cook a kid in its mother's milk" three times. Why the repetition?

Here, the Sifrei offers another fascinating interpretation: These three instances correspond to the three covenants (britot) that God made with Israel. Think of them as landmark moments in the relationship between God and the Jewish people.

One covenant was made at Chorev (another name for Mount Sinai), a pivotal moment of revelation and lawgiving. Another took place in the plains of Arvoth Moav, just before the Israelites entered the Promised Land. And the third happened at Mount Gerizim and Mount Eival, where blessings and curses were proclaimed to the people.

So, what does it all mean? The repetition of this seemingly simple law becomes a powerful reminder of the enduring bond between God and Israel, sealed through multiple covenants. It suggests that even the seemingly mundane laws are deeply intertwined with the very foundation of our relationship with the Divine.

It's a small passage, but it opens a window into the world of rabbinic interpretation: the careful attention to detail, the weaving together of seemingly disparate ideas, and the constant search for deeper meaning in the text. And, perhaps, it gives us a little more appreciation for that cheeseburger we can't have.
