Symbolically, or in Biblical types....the Pharoah is Satan and Egypt is the world with it's carnal lusts. As the Pharaoh is Satan...who is his daughter?
What does that river represent? Satan's deception, his poisoning of the living water of truth. Moses was nourished by Pharaoh's daughter, as we are, by all she has to offer.....
- Exodus 2:5-6 And the daughter of Pharaoh came down to wash herself at the river; and her maidens walked along by the river's side; and when she saw the ark among the flags, she sent her maid to fetch it. And when she opened it, she saw the child: and, behold, the babe wept. And she had compassion on him, and said, "This is one of the Hebrews' children."

- Acts 7:21 And when he was cast out, Pharaoh's daughter took him up, and nourished him for her own son.
- Hebrews 11:24 By faith Moses, when he was come to years, refused to be called the son of Pharaoh's daughter;
- 1 Kings 3:1 And Solomon made affinity with Pharaoh king of Egypt, and took Pharaoh's daughter, and brought her into the city of David, until he had made an end of building his own house, and the house of the LORD, and the wall of Jerusalem round about.
- 1 Kings 7:8 And his house where he dwelt had another court within the porch, which was of the like work. Solomon made also an house for Pharaoh's daughter, whom he had taken to wife, like unto this porch. 9:24 But Pharaoh's daughter came up out of the city of David unto her house which Solomon had built for her: then did he build Millo.
- Mark 13:1 And as He went out of the temple, one of His disciples saith unto Him, "Master, see what manner of stones and what buildings are here!" And Jesus answering said unto him, "Seest thou these great buildings? there shall not be left one stone upon another, that shall not be thrown down."
