What Does Exodus 14:22 Mean?

And the people of Israel went into the midst of the sea on dry ground, the waters being a wall to them on their right hand and on their left. The sea crossing narrative's central image, "walls of water on their right hand and on their left, dry ground beneath their feet", is the most physically impossible description in the Exodus account and the one that has generated the most interpretive discussion. The "walls" (Hebrew: chomah, wall/barrier) of water are rather than parted waters that provide a channel; they are walls: vertical masses of water held in place against natural physics while Israel walks between them on dry ground.

The "dry ground" (Hebrew: bayyabashah, on the dry/solid ground) is the miracle's physical requirement: not damp sand, not mud, not shallow water passable with wading, but dry ground: walkable, firm, carrying the weight of a million-plus people and their livestock. The sea bed must have been dry enough for the livestock (Exodus 10:26's "not a hoof shall be left behind": the animals are crossing too) and for the practical movement of a massive community. The dry ground within the walls emphasizes the total reversal of the sea's normal state: the water is above-ground (walls), the ground is dry.

Paul's baptism typology in 1 Corinthians 10:1-2 reads the sea crossing as Israel's "baptism into Moses in the cloud and in the sea": the cloud above and the sea around Israel during the crossing creates the baptismal immersion image. The water that surrounded Israel (walls on both sides, cloud above) without touching them is the typological prototype of baptism: immersed in water while being protected from it, emerging on the other side as a new people. Peter similarly connects the Flood's waters-saving-through-judgment to baptism (1 Peter 3:20-21); Paul extends the same typological logic to the sea crossing.
