Arcana Coelestia # 8681
8681. And Aaron came, and all the elders of Israel. That this signifies the things of the church which are primary, is evident from the representation of Aaron, as being the truth of doctrine (see n. 6998, 7009, 7089, 7382); and from the representation of the elders of Israel, as being the chief truths of the church that are in agreement with good (n. 6524, 8578, 8585); for by “Israel” is signified the church (n. 8645).
Arcana Coelestia # 7009
7009. And it shall be that he shall be to thee for a mouth. That this signifies the truth of doctrine, which also proceeds mediately from the Lord, is evident from the representation of Aaron, who was to be “to Moses for a mouth,” as being doctrine (see n. 6998); and from the signification of “being to Moses for a mouth,” as being his utterance or preaching (n. 6987). It is said the truth of doctrine which also proceeds mediately from the Lord, because the truth of doctrine, which is represented by Aaron, is such as is heard and perceived by angels and men. This truth is what proceeds mediately from the Lord; but the truth which is represented by Moses, is that which proceeds from the Lord immediately, and is not heard or perceived by men, nor even by angels (n. 6982, 6985, 6996, 7004).
