12 For each one cast down his rod, and they became dragons; but Aaron’s rod swallowed up their rods.
13 And Pharaoh’s heart became hard, that he hearkened not unto them as the Lord had said.
14 Then the Lord said unto Moses, Pharaoh’s heart is become grievous, for he refuses to let the people go.
15 Go unto Pharaoh in the morning; behold, he goes out unto the water; and thou shalt stand by the river’s brink before him and take in thy hand the rod which was turned to a serpent
