Arcana Coelestia#8795
8795. 'Saying, Take care not to go up into the mountain' means that there must be no extension whatever to celestial communities which have the love of good. This is clear from the meaning of 'going up' as extending to the Divine as He exists in a higher heaven; and from the meaning of 'the mountain' as the good of love there, dealt with in 4210, 6435, 8327, 8758. The nature of all this is clear from the explanation immediately above in 8794.
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.
