A turban symbolizes intelligence and wisdom. Aaron's turban of ordinary linen, mean the intelligence that is related to natural truth. See Leviticus 16:4; Ezekiel 44:18. Things made of 'linen' or 'flax' signify truth in the natural level of a person's mind. (Arcana Coelestia 7601)

'A turban' signifies intelligence of truth.

10580. 'And Jehovah said, Behold, there is a place by Me, and you shall stand on the rock' means a state of faith in God. This is clear from the meaning of 'a place' as a state, dealt with in 2625, 2837, 3356, 3387, 4321, 4882, 5605, 7381, 9440, 9967, 10146; and from the meaning of 'the rock' as faith, dealt with in 8581, 10438, the reason why a state of faith in God is meant being that the words 'a place by Me' are used. No one can know except from the internal sense that this is the meaning of these words, thus unless he knows what it is that 'a place' means and what it is that 'the rock' means in that sense. But for the internal sense what would the declaration that there was a place by Jehovah on the rock mean? It would mean that Jehovah dwelt there and was providing Moses a place by Him; but in fact Jehovah dwells in heaven among angels, and in the Church among people. The meaning of 'the rock' as faith has its origin in the things that appear in the next life; those ruled by faith dwell there on rocks, but those governed by love dwell on mountains. The rocks there are stony in appearance; but not so the mountains, because they are raised up masses of earth. This is where the meaning of 'the rock' as faith comes from.
