9 When Pharao shall say to you, Shew signs: thou shalt say to Aaron: Take thy rod, and cast it down before Pharao, and it shall be turned into a serpent.
10 So Moses and Aaron went in unto Pharao, and did as the Lord had commanded. And Aaron took the rod before Pharao, and his servants, and it was turned into a serpent.
11 And Pharao called the wise men and the magicians: and they also by Egyptian enchantments and certain secrets did in like manner.
12 And they every one cast down their rods, and they were turned into serpents: but Aaron's rod devoured their rods.
13 And Pharao's heart was hardened, and he did not hearken to them, as the Lord had commanded.
14 And the Lord said to Moses: Pharao's heart is hardened, he will not let the people go.
15 Go to him in the morning, behold he will go out to the waters: and thou shalt stand to meet him on the bank of the river: and thou shalt take in thy hand the rod that was turned into a serpent.
