'Rivers' in the Bible

Then the Lord said to Moses, “Say to Aaron, ‘Take your staff and stretch out your hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their reservoirs of water, that they may become blood; and there will be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.’”

Then the Lord said to Moses, “Say to Aaron, ‘Stretch out your hand with your staff over the rivers, over the streams and over the pools, and make frogs come up on the land of Egypt.’”
