It’s a declaration, a relationship. And Shemot Rabbah, the great collection of homiletical teachings on the Book of Exodus, offers some profound insights into why this phrasing is so crucial.

Rabbi Abbahu begins with an analogy: Imagine an earthly king. He has power, yes, but he also has a family. A father, brothers, perhaps even an heir apparent. These relatives share in his glory, and they ensure the continuity of the throne. But the Holy One, blessed be He, is different.

"I am first," God says, as we read in Isaiah (44:6), "as I have no father; and I am last, as I have no brother; and besides Me there is no God, as I have no son." It's a powerful statement of uniqueness. God isn't part of a lineage, a dynasty. God is. Absolute and without peer. This isn’t just about divine ego. It’s about the very nature of God’s being. There's no one before, no one after, no one beside.

But there's more to it than just that. Shemot Rabbah goes on to unpack the verse "I am the Lord your God" through another lens, connecting it to the Exodus itself. "I related, I saved, and I announced…" (Isaiah 43:12), God says.

"I related," meaning God orchestrated events in Egypt so that the Egyptians would hear of the Israelites' flight, pursue them, and ultimately meet their end in the Sea of Reeds, the Yam Suf. Remember, "It was told to the king of Egypt that the people had fled" (Exodus 14:5).

"I saved" – a direct reference to the miraculous deliverance at the sea: "The Lord saved Israel on that day" (Exodus 14:30).

And "I announced" – meaning God’s power was made known to the surrounding nations, causing them to tremble in fear, as we see in the Song of the Sea: "Peoples heard, they were agitated" (Exodus 15:14).

The text then adds a subtle but fascinating detail: "There was no stranger among you" (Isaiah 43:12). This is linked to the story of Moses sending his father-in-law, Jethro, away (Exodus 18:27). The implication? To truly experience this moment, this revelation at Sinai, one had to be fully part of the Israelite community. Immediately after this departure, "In the third month [from the exodus of the children of Israel from the land of Egypt, on that day they came to the wilderness of Sinai]" (Exodus 19:1). The timing is significant.

Ultimately, the passage circles back to the core idea: "You are My witnesses, the utterance of the Lord, and I am God" (Isaiah 43:12). It's a reciprocal relationship. God acted, God saved, and now, the Israelites are witnesses to that divine power. Their very existence, their freedom, is proof of God's sovereignty.

So, what does it all mean? Perhaps it's this: The opening declaration of the Ten Commandments isn't just a statement of power, but a statement of relationship, forged in the crucible of slavery and redemption. It's an invitation to witness, to remember, and to recognize the unique, unparalleled presence of God in our lives. And it reminds us that this relationship demands a certain level of commitment, a willingness to be present and fully engaged in the unfolding story of faith.
