Exodus 7:13-15

KJ2000(i) 13 And he hardened Pharaoh's heart, that he hearkened not unto them; as the LORD had said. 14 And the LORD said unto Moses, Pharaoh's heart is hardened, he refuses to let the people go. 15 Get you unto Pharaoh in the morning; lo, he goes out unto the water; and you shall stand by the river's bank until he comes; and the rod which was turned to a serpent shall you take in your hand.
