"first plague" - "Pharaoh’s heart is hard; he refuses 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 'against he come;' and the rod which was turned to a serpent shalt thou take in thine hand." 'and stretch out your hand over the 'waters of Egypt' - they shall be turned to blood.
