Arcana Coelestia # 6149
6149. 'For the priests had a fixed portion from Pharaoh' means that this had therefore been decreed by the natural, which was under the control of the internal. This is clear from the meaning of a 'fixed portion' as that which has been decreed, and from the representation of 'Pharaoh" as the natural in general, dealt with in 5160, 5799, 6015. And since that decree made in the natural originated in the internal, the description 'under the control of the internal' is added, which control was also represented by Joseph's being lord over the whole of Egypt, and over Pharaoh's house too, see 6145.

6142. 'And Joseph bought all the ground of Egypt for Pharaoh' means that [the internal] made the entire natural mind where factual knowledge resides its own and placed it under its overall control. This is clear from the representation of 'Joseph' as the internal, dealt with often; from the meaning of 'buying' as making one's own, dealt with in 4397, 5374, 5797, 5406, 5410, 5426; from the meaning of 'the ground of Egypt' as the natural mind where factual knowledge resides, dealt with immediately above in 6141; and from the representation of 'Pharaoh' as the natural in general, dealt with in 5160, 5799, 6015. Thus the acquisition of that ground for Pharaoh means placing under an overall control in the natural.
