Apocalypse Revealed # 45
45. Clothed with a long robe. This symbolizes the emanating Divinity which is Divine truth.
A long robe symbolizes the emanating Divinity which is Divine truth because garments in the Word symbolize truths. Thus a long robe, being an outer garment, symbolizes, when said of the Lord, Divine truth emanating.
Garments in the Word symbolize truths because people in heaven are clothed in accordance with the truths emanating from their goodness, on which subject see the book Heaven and Hell (London, 1758), nos. 177-182.
In subsequent explanations we will see that garments in the Word mean nothing else in its spiritual sense, accordingly that nothing else is meant by the Lord's garments when He was transfigured, which appeared as white as the light (Matthew 17:1-4, Mark 9:2-8, Luke 9:28-36). So, too, neither is anything else meant by the Lord's garments which the soldiers divided (John 19:23-24).
In Arcana Coelestia (The Secrets of Heaven), published in London, it may be seen that the like was represented and so symbolized by Aaron's garments (nos. 9814 10067); in particular, by the ephod (nos. 9477 9824, 10005), the robe (nos. 9825 10005), the tunic (nos. 9826 9942), and the turban (no. 9827). For Aaron represented the Lord's priestly function.
Regarding the symbolism of garments in the Word, see nos. 166 and 328 below.
