1025. And the mountains were not found. That this signifies that there was no longer any good of love, is evident from the signification of mountains, as denoting the church as to the good of love (concerning which see (n. 405, 510, 850). The reason why mountains denote the church as to the good of love is, that the earth signifies the church; and the angels who are in love to the Lord inhabit mountain lands in the spiritual world. Hence mountains signify the church as to the good of love to the Lord.

These dwell upon mountains in the spiritual world because they are interior angels; and interior things in the spiritual world correspond to higher things, and actually become higher. This is why the Lord, being in the inmost, is called the Highest, and is said to dwell in the highest.

Concerning the Precepts of the Decalogue in general:-

[2] What these three senses are in the Precepts of the Decalogue may be further seen from the following summary exposition. The first precept, "Thou shalt not worship other gods besides me," in the spiritual moral sense involves, that thou shalt not worship any other thing or any other person as Divine. It is said no other thing, that is, not to ascribe to nature anything Divine of itself; nor to any other person, namely, any vicar of the Lord; or any saint. In the celestial-spiritual sense it involves that thou shalt acknowledge only one God, and not several, according to their characters, as did the ancients, and as some pagans do at this day, or according to the works of each, as do the Christians at this day, who set up one God of creation, one of redemption, and one of enlightenment.

[3] The same precept in the Divine-celestial sense involves that the Lord alone is to be acknowledged and worshipped; and the Trinity in Him, namely, the Divine itself from eternity, meant by the Father; the Divine Human born in time, meant by the Son of God, and the Divine proceeding from both, meant by the Holy Spirit.

These are the three senses of the first precept in their order.

[4] From this precept, considered in its threefold sense, it is evident that in it are contained and included, in summary, everything concerning the Divine as to Essence. In the other precept, "Thou shalt not profane the name of God," in its three senses are contained and included everything concerning the Divine as to quality. For by the name of God is signified His quality, which, in a primary sense, is the Word; from the Word, doctrine, and from doctrine, worship of the lips and of the life. In the second sense, it is the Lord's kingdom on the earth and the Lord's kingdom in the heavens; and in the third sense, it is the Lord's Divine Human; for this is the quality of the Divine Itself. That the Lord's Divine Human, in the highest sense, is the name of God, may be seen above (n. 224).

In the rest of the precepts there are similarly three internal senses for the three heavens. But of these, the Lord willing, we shall treat elsewhere.
