'Rivers' in the Bible

And Jehovah said to Moses, Say unto Aaron, Take thy staff, and stretch out thy hand upon the waters of the Egyptians upon their streams, upon their rivers, and upon their ponds, and upon all their reservoirs of water, that they may become blood; and there shall be blood throughout the land of Egypt, both in vessels of wood and in vessels of stone.

And Jehovah said to Moses, Say unto Aaron, Stretch out thy hand with thy staff over the streams, over the rivers, and over the ponds, and cause frogs to come up on the land of Egypt.
