Rabbi Bana'ah taught that God split the Red Sea for the Israelites in the merit of their ancestor Abraham. The proof lies in a striking verbal parallel between two verses. When Abraham bound his son Isaac for the offering on Mount Moriah, the Torah says "he split the wood for the burnt-offering" (Genesis 22:3). And at the sea, the Torah says "the waters were split" (Exodus 14:21).
The shared Hebrew root, the verb "to split," is not a coincidence in rabbinic eyes. It is a divine signal that the two events are linked by a chain of merit. Abraham's willingness to split wood for the most painful sacrifice imaginable, the offering of his own son, generated a reservoir of spiritual credit that his descendants drew upon centuries later at the shore of the sea.
This teaching reflects a foundational concept in Jewish thought known as zekhut avot, the merit of the ancestors. The righteous deeds of Abraham, Isaac, and Jacob do not expire. They accumulate like a spiritual inheritance, available to future generations in their moments of greatest need. When the Israelites stood trapped between the Egyptian army and the sea, they had no merit of their own sufficient for such a miracle. They had been slaves, steeped in Egyptian culture. But Abraham's ancient act of devotion still echoed in Heaven.
Rabbi Bana'ah's teaching also implies a measure-for-measure dynamic. Abraham split something physical, wood, in service of God. God responded by splitting something far grander, an entire sea, in service of Abraham's children. The small, faithful act generates a cosmic response.
