10And Moses and Aaron went in unto Pharaoh, and they did so as the LORD had commanded: and Aaron cast down his rod before Pharaoh, and before his servants, and it became a serpent. 11Then Pharaoh also called the wise men and the sorcerers: now the magicians of Egypt, they also did in like manner with their enchantments. 12For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods. 13And he hardened Pharaoh's heart, that he hearkened not unto them; as the LORD had said.14And the LORD said unto Moses, Pharaoh's heart is hardened, he refuseth to let the people go. 15Get thee unto Pharaoh in the morning; lo, he goeth out unto the water; and thou shalt stand by the river's brink against he come; and the rod which was turned to a serpent shalt thou take in thine hand. 16And thou shalt say unto him, The LORD God of the Hebrews hath sent me unto thee, saying, Let my people go, that they may serve me in the wilderness: and, behold, hitherto thou wouldest not hear.
