6730. 'To wash at the river' means worship involving the use of falsity. This is clear from the meaning of 'washing' as purification from what is understood spiritually by filth, dealt with in 3147, worship consequently being meant since worship takes place for the sake of purification; and from the meaning of 'the river', in this case the river of Egypt, as falsity, dealt with in 6693.

5799. 'For as you are, so is Pharaoh' means that he has control over the natural. This is clear from the representation of 'Pharaoh' as the natural in general, dealt with in 5160; and from the representation of 'Joseph' as the internal, dealt with previously. The control exercised by the internal over the natural is represented by Joseph's being placed in charge over all the land of Egypt as well as over the whole of Pharaoh's house, Genesis 41:40-41.
