6153. 'Behold, I have bought you today, and your ground, for Pharaoh's house means that it had obtained those things for itself and had made them subject to the general whole within the natural, which was under the control of the internal. This is clear from the meaning of 'buying' as making one's own and acquiring, dealt with in 4797, 5374, 5397, 5406, 5410, 5426; and from the meaning of 'ground' as the receptacles of truth, dealt with in 6135-6137; and the subjection of those receptacles to the general whole in the natural is meant by 'his buying them for Pharaoh' who represents the natural in general, dealt with in 5160, 5799, 6015. The use of the expression 'under the control of the internal' is in keeping with the explanation above in 6145.
