Take the covenant God makes with Abraham in Genesis 15. It's a big moment, right? God promises Abraham this whole huge swathe of land for his descendants. But then it gets…well, geographically detailed. "From the river of Egypt to the great river Euphrates" (Genesis 15:19). Why those rivers? Why not just say "all this land" and be done with it?

That, my friends, is the question at the heart of Midrash of Philo 18.

Now, when we say Midrash, what do we mean? Midrash (מדרש) is, at its heart, interpretation. It's how the Rabbis, and Jewish thinkers throughout the ages, have delved into the Torah, wrestling with its words, teasing out hidden meanings, and making it relevant for every generation. And Philo? Well, Philo of Alexandria was a Jewish philosopher living in the first century. His work attempts to synthesize Jewish scripture with Greek philosophy. This particular Midrash attributed to him tackles this very question of the covenant's boundaries.

So why those rivers?

The Midrash doesn't give us a simple, straightforward answer. Instead, it invites us to consider what those boundaries represent. It's not just about a map, is it? It's about something deeper.

Could it be about defining the scope of influence, perhaps? The promise isn’t just about physical territory, but also about the spiritual and cultural impact that Abraham's descendants would have. Think about it: rivers, in ancient times, were not only sources of life and sustenance, but also borders, pathways for trade and communication, arteries of civilization.

Or maybe it's about setting limits – both geographical and perhaps even moral or ethical. The promise, while vast, isn't limitless. There's a defined space, a framework within which this covenant operates. It's a reminder that even with divine blessing, there are boundaries and responsibilities.

Perhaps the specification of the rivers is a form of precision meant to convey the certainty of the promise. There's no wiggle room, no ambiguity. God isn't vague; God is specific. This isn't just any land; it's this land.

Sometimes, the power isn't in knowing the definitive answer, but in the asking of the question itself. The Midrash of Philo 18, in its brevity, invites us to contemplate the depth and complexity of God's covenant with Abraham. It pushes us to look beyond the literal, to see the layers of meaning embedded in the sacred text. And that, perhaps, is the whole point of Midrash in the first place.
