How God Dealt With Moses in Mercy and the Fathers in Judgment

There is a moment in the Song at the Sea where Israel calls God "Keli," my God, and then immediately follows with "Elokei avi," the God of my father. Two names. Back to back. The same God, referred to twice in a single breath, by two different titles.

The Mekhilta DeRabbi Yishmael, in Tractate Shirah 3:18, refuses to treat this as stylistic variation. The two names mean different things. They describe different modes of divine engagement. The distinction the Mekhilta draws here is one of the more delicate pieces of theological work in the entire Song at the Sea tradition.

Two Names and What They Carry

"Keli," the Mekhilta teaches, connotes the attribute of mercy. "Elokei," the divine name rooted in the word for power and judgment, connotes the attribute of justice. The rabbis prove this from three verses. "Keli, Keli, why have You forsaken me?" (Psalms 22:2), the great cry of abandonment that carries within it the hope of return. "Kel, I pray You, heal her, I pray You" (Numbers 12:13), Moses's desperate prayer for Miriam after she was struck with skin disease. "The Lord is Kel, and He has lighted the way for us" (Psalms 118:27). Each instance of this name appears in a context of appeal, of pleading, of mercy extended to a suffering person. The name carries warmth.

The name "Elokei," by contrast, is proved from Deuteronomy 1:17: "For the judgment is to Elokei." This name carries weight and authority and the expectation of accounting.

So when Israel at the Red Sea says "Keli" and then "Elokei avi," they are making a precise statement: with me, God manifested mercy. With my fathers, God manifested justice.

Why Did the Patriarchs Get Justice and Moses Get Mercy?

This is the question the Mekhilta leaves open, which is itself a rabbinic technique. State the distinction. Let the reader turn it over. The text does not explain why Abraham, Isaac, and Jacob encountered God primarily through the attribute of judgment while the generation of the Exodus encountered God primarily through mercy. But the distinction is grounded in Scripture, and the Scripture does not lie.

One reading is historical. The patriarchs lived in a world that was still being constructed, where covenants were being established, where the terms of the relationship between God and this particular family were being worked out. Judgment is the language of formation, of setting boundaries, of defining what is permitted and what is not. The generation of Moses lived in a world where the covenant existed but the people were broken. Slaves in a foreign country, stripped of their history, uncertain of their identity. Mercy is the language of restoration, of healing what has been damaged, of drawing back what has wandered.

Other passages in Tractate Shirah explore the many attributes through which God is praised in the Song at the Sea: wise, rich, merciful, a judge, comely, glorious. The rabbis reading Exodus 15 found a complete portrait of divine character distributed through the verses of the poem. The distinction between mercy and justice was not the only one. It was one thread in a larger theology of how God relates to Israel across different historical conditions.

The Song of Songs Frame

The Mekhilta precedes its analysis with a passage from Song of Songs: "I had almost passed them by, when I found Him whom my soul loved. I held onto Him and did not let go of Him until I had brought Him to the house of my mother and the chamber of my conception." The "them" in this passage is identified as Moses and Aaron, the two figures who mediated the Exodus. The verse imagines Israel nearly missing the encounter with God, nearly losing the moment of redemption, and then seizing it and refusing to let go.

That image of holding on illuminates the theological claim that follows. The distinction between mercy and judgment, between Keli and Elokei, is not a division between a harsh old God and a compassionate new one. It is a description of how God adapts engagement to circumstance. The patriarchs needed to learn the terms of the covenant. The Exodus generation needed to survive. The God of mercy who met Israel at the Red Sea is the same God of justice who met Abraham at the covenant between the pieces. The relationship holds across both modes.

The name you use for God reveals what you are asking of God. Israel at the sea called out to the God of mercy because mercy was what they needed. They had been slaves. The accounting could come later. First, they needed to be brought through the water. The Mekhilta preserves this as wisdom about prayer: know which attribute you are addressing, know what the moment requires, and call the name that fits the need.
