7644. And it shall cover the surface of the land. That this signifies the ultimates of the natural mind, is evident from the signification of “the surface,” as being things external, thus ultimate; and from the signification of “the land,” here the land of Egypt, as being the natural mind (see n. 5276, 5278, 5280, 5288, 5301).

7269. Also Aaron thy brother shall be thy prophet. That this signifies the doctrine thence derived, is evident from the signification of a “prophet,” as being the truth of doctrine, thus doctrine from the Word (see n. 2534). (That Aaron represents the doctrine of the church, or the doctrine of good and truth which is from the Word, see n. 6998, 7009, 7089.) As a “prophet” signifies doctrine, in a determinate sense it signifies one who teaches, according to what was said just above (see n. 7268 at the end).
