*]Why did Moses turn his staff into a snake rather than into something else, and why did his snake eat up the other two? Was it because snakes meant something in Egyptian culture?
Minor trivia: despite the portrayals in
The Ten Commandments (1956) and
The Prince of Egypt (1998), it was actually
Aaron’s staff that turned into a ‘serpent’ (though see my further comments below for another possibility). In fact, if you read through Exodus, it was actually Aaron who acts at Moses’ bidding, who in turn receives commands from God. The only plagues where God does things Himself and both Moses and Aaron do not actively do anything are the flies (8:20-30), the livestock (9:1-7), and the death of the firstborn (12:29-32).
Turning the Nile to blood? That had Moses commanding Aaron (7:14-25). Frogs? Aaron stretched out his hand at Moses’ instructions (8:1-15). Gnats? Aaron struck the dust with his staff (8:16-19). Boils? Apparently both Moses
and Aaron take the handfuls of soot (9:8-12). Moses only takes over in the latter half, during the plagues of hail (9:13-34), locusts (10:1-20) and darkness (10:21-29), where he is the one commanded to stretch out his staff (9:22-23; 10:12-13, 21-22).
Then the LORD said to Moses and Aaron, “When Pharaoh says to you, ‘Prove yourselves by working a miracle,’ then you shall say to Aaron, ‘Take your staff and cast it down before Pharaoh, that it may become a serpent.’” So Moses and Aaron went to Pharaoh and did just as the LORD commanded. Aaron cast down his staff before Pharaoh and his servants, and it became a serpent. Then Pharaoh summoned the wise men and the sorcerers, and they, the magicians of Egypt, also did the same by their secret arts. For each man cast down his staff, and they became serpents.
But Aaron’s staff swallowed up their staffs. Still Pharaoh’s heart was hardened, and he would not listen to them, as the LORD had said.
The Egyptians
were very big on snakes, you see. Snakes were literally everywhere in ancient Egypt, including the desert sands, in old walls, in fields, by the Nile and in its swamps, on threshing floors, in houses and in livestock enclosures and pastures, and poisonous snakes posed a threat to humans and domestic animals alike. Hence, the Egyptians had somewhat of a love/hate relationship with snakes. So for them, the serpent is at once a good (cf. the goddess Wadjet) and a bad symbol (cf. the sun god Re’s sibling and enemy, the serpent
Apep).
As an aside, I have another trivia for you. The word usually translated in this context,
tannin, is a different word from that used in Exodus 4:3 when Moses’ staff turned into a
nachash (the word for ‘snake’).
BTW, there’s a suggestion that the word
tannin here should be understood as referring to, not to a snake (
nachash; cf. Exodus 4:3), but to another creature such as a crocodile, since the word
tannin refers to a larger reptile (in some texts large river or sea or land creatures!) The Greek also makes this distinction: Moses’ staff turns into an
ophis (snake) but Aaron’s turns into a
drakōn!
Crocodiles are actually both deeply feared and worshipped (cf. the god
Sobek) in the nation so dependent on the Nile River, regarded simultaneously as a voracious devourer (think for example of
Ammit of Egyptian mythology, who has a body that was part lion and part hippopotamus, with the head of a crocodile) and a warder of evil in ancient Egyptian thought, so the imagery might be quite fitting. Imagine: Aaron throws his rod, which turns into this crocodile which eats up all the staves of the diviners of Egypt!
