6998. And He said, Is there not Aaron thy brother the Levite? That this signifies the doctrine of good and truth, is evident from the representation of Aaron, as being the Lord as to Divine good or the priesthood; but here, before he was initiated into the priesthood, the doctrine of good and truth: and therefore also it is said that "he should be to Moses for a mouth, and Moses to him for God;" for by Moses is represented the Lord as to the Divine truth which proceeds immediately from the Lord; consequently by Aaron, the Divine truth which proceeds mediately from the Lord, and which is the doctrine of good and truth. That truth which Moses here represents is truth which cannot be heard or perceived by man (n. 6982); but the truth which Aaron represents is truth which can be both heard and perceived by man; hence Aaron is called the "mouth," and Moses his "God;" and hence Aaron is called a "Levite," for by a "Levite" is signified the doctrine of good and truth of the church, which ministers to and serves the priesthood.
