And He said, “Cast it on the ground.” So he cast it on the ground, and it became a serpent; and Moses fled from it.

“When Pharaoh speaks to you, saying, ‘Show a miracle for yourselves,’ then you shall say to Aaron, ‘Take your rod and cast it before Pharaoh, and let it become a serpent.’ ”

So Moses and Aaron went in to Pharaoh, and they did so, just as the Lord commanded. And Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.

For every man threw down his rod, and they became serpents. But Aaron’s rod swallowed up their rods.

Go to Pharaoh in the morning, when he goes out to the water, and you shall stand by the river’s bank to meet him; and the rod which was turned to a serpent you shall take in your hand.
