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.
16 And thou shalt say to him: The Lord God of the Hebrews sent me to thee saying: Let my people go to sacrifice to me in the desert: and hitherto thou wouldst not hear.
17 Thus therefore saith the Lord: In this thou shalt know that I am the Lord: behold I will strike with the rods that is in my hand, the water of the river, and it shall be turned into blood.
18 And the fishes that are in the river shall die, and the waters shall be corrupted, and the Egyptians shall be afflicted when they drink the water of the river.
