Exodus 7:14-15
Exodus 7:14-15 ASV
And Jehovah said unto Moses, Pharaoh’s heart is stubborn, he refuseth to let the people go. Get thee unto Pharaoh in the morning; lo, he goeth out unto the water; and thou shalt stand by the river’s brink to meet him; and the rod which was turned to a serpent shalt thou take in thy hand.
