What Does Exodus 4:3 Mean?

He said, "Throw it on the ground." So he threw it on the ground, and it became a serpent, and Moses fled from it. The first sign converts the symbol of Moses' pastoral authority (the staff) into the symbol of primal danger (The serpent) and then back again (verse 4).

The serpent (Hebrew: nachash) is the same word used for the creature in the Garden of Eden, the creature associated with deception and danger in the Hebrew imagination. The staff that represents Moses' own capacity and competence suddenly becomes something dangerous and independent: it moves on its own, it is an animal, it threatens. Moses' flight from his own staff illustrates the gap between Moses' capacity and the divine power that will attend his mission.

The conversion of a staff into a serpent will be replicated when Moses stands before Pharaoh in chapter 7. There, Aaron throws Moses' staff before Pharaoh and it becomes a serpent; Egypt's magicians replicate the sign with their staffs, but Moses' serpent swallows all the others. What is rehearsed privately at the burning bush is performed publicly before the greatest power in the ancient world. God teaches Moses privately, in the wilderness, the signs that will be performed before Pharaoh's court. No performance before the king was unrehearsed; the Exodus miracles were prepared.

The serpent in the ancient Near Eastern context carried royal associations: the uraeus, the rearing Cobra, was the crown symbol of Egyptian Pharaoh, and serpent imagery pervaded Egyptian royal and divine iconography. When Moses' staff becomes a serpent, and when in chapter 7 it swallows Egypt's serpents, the sign carries a specific political-theological dimension: the power of YHWH is greater than the serpent-power of Pharaoh's divine pretensions. The sign given at the burning bush to authenticate Moses before Israel is also a sign that will directly challenge Egypt's royal symbolism.
