9374. Thou and Aaron. That this signifies the Word in the internal sense and the external sense, is evident from the representation of Moses, as being the Word (of which above, n. 9372). But when Aaron, who was his brother, is joined to him, then Moses represents the Word in the internal sense, and Aaron the Word in the external sense (as also above, n. 7089, 7382).

In Genesis 2:24, this signifies to separate from the internal man. (Arcana Coelestia 160)

In Genesis 44:22, this signifies to separate truth from spiritual good, which cannot be done, or else the church perishes. (Arcana Coelestia 5812-5813)

In Genesis 50:8, this signifies that the goods of innocence and charity, interior and exterior, remained in the inmost parts of man. (Arcana Coelestia 6532)

7382. Stretch forth thy hand with thy rod. That this signifies the power of internal truth through external truth, is evident from the signification of “hand,” as being spiritual power, which is that of internal truth; and from the representation of a rod, as being natural power, which is that of external truth (see n. 6947, 6948). (That all power in the spiritual world belongs to truth, see n. 3091, 3387, 4931, 6344, 6423, 6948.) As Moses represents the internal law, which is the same as internal truth, and Aaron represents the external law, which is the same as external truth, and as internal truth flows into external and gives it power (n. 7381), therefore by the word of Moses to Aaron, “Stretch forth thy hand with thy rod,” is signified the power of internal truth through external truth.
