That this signifies extension through the whole natural where memory-knowledges are, is evident from the meaning of the expression, “from one end of the border to the other end thereof,” as being extension through the whole; and from the signification of “Egypt,” as being memory-knowledge in the natural (of which often above), thus the natural where memory-knowledges are. For the natural is what contains, and memory-knowledges are what are contained. Thus by “Egypt” is signified both what contains and what is contained, that is, both the natural and the memory-knowledge. Wherefore also by “Pharaoh the king of Egypt,” is signified the natural in general (n. 5160, 5799), and also memory-knowledge in general (n. 6015); and by the “land of Egypt,” the natural mind (n. 5276, 5278, 5280, 5288, 5301).
