Shemot Rabbah, that incredible collection of Midrashim (interpretive stories) on the Book of Exodus, offers a fascinating insight into just this question. It all starts with a seemingly simple verse: "This is the matter that you shall do to them to sanctify them to serve as priests to Me: Take one young bull and two rams, unblemished" (Exodus 29:1). The rabbis, in their infinite wisdom, don't just take this verse at face value. They see a much deeper meaning.
They connect this verse to a powerful declaration from the Book of Psalms: "Forever, Lord, Your word stands in the heavens" (Psalms 119:89). King David, in this psalm, isn’t just making a nice statement. He’s drawing a parallel, a profound connection between God’s very essence and God’s spoken word. As David says, "Just as You are truth, as it is stated: 'The Lord God is truth' (Jeremiah 10:10), so Your word is truth."
But here's where it gets really interesting. The rabbis take a little linguistic turn. Instead of reading "bashamayim"—"in the heavens"—they suggest we read it as "kashamayim"—"like the heavens." It’s a subtle shift, playing on the visual similarity between the Hebrew letters bet and kaf. What does this change do? It transforms the verse's meaning.
Now, it's not just saying God's word is in the heavens, but that it is like the heavens. Just as God spoke in the beginning and the heavens came into being, so too, God's word regarding the sanctification of Aaron and his sons will endure forever. It's a decree as powerful and permanent as the cosmos itself!
And this isn't just some fleeting idea. It's tied to the very concept of covenant. As Numbers 25:13 tells us, this priesthood is "for him and for his descendants after him a covenant of an eternal priesthood." God's promise, once made, is unbreakable.
Why is this so? The Midrash brings in Isaiah 55:11: "So will be My word [devari] that emerges from My mouth; [it will not return to Me unfulfilled]." God's word, once spoken, has a purpose. It has power. It will be fulfilled. It cannot be undone. That’s why the Torah says, "This is the matter [davar]."
So, what does this all mean for us today? It's a reminder that words have weight. God's words, especially, are not empty pronouncements. They are declarations of intent, promises etched into the fabric of reality. When we read these ancient texts, we're not just reading history, we're tapping into a living, breathing covenant that continues to shape our world. And perhaps, it's a reminder to consider the power of our own words as well.
