Arcana Coelestia #9388
9388. 'And built an altar under the mountain' means a representative sign of the Lord's Divine Human in respect of Divine Good from Him. This is clear from the meaning of 'an altar' as a representative sign of the Lord's Divine Human, dealt with in 921, 2777, 2811, 4489, and therefore the chief representative of worship of the Lord, 4541, 8935, 8940; and from the meaning of 'the mountain' as the good of love, dealt with in 4210, 6435, 8327, 8658, 8758, in this instance the Divine Good of love which emanates from the Lord, since it was Mount Sinai, where the Lord was then. 'Mount Sinai' means Divine Good united to Divine Truth emanating from the Lord, see 8805.
Arcana Coelestia #8758
8758. 'And Israel encamped beside the mountain' means an arrangement effected by Divine heavenly good among those belonging to the spiritual Church. This is clear from the meaning of 'encamping' as an arrangement, as above in 8757; from the representation of 'Israel' as those who belong to the spiritual Church, also dealt with above, in 8751; and from the meaning of 'the mountain' as the good of heavenly love, dealt with in 4210, 6435, 8327. The words 'Divine heavenly good' are used to mean good from God as it exists in heaven; for that good as it exists in itself is far above heaven.
