Jerusalem, on Mount Zion, signifies the doctrine of love to the Lord, and how it governs your life. Jerusalem first comes to our attention in 2 Samuel 5, when King David takes the city from the Jebusites and makes it his capital. In the next chapter he brings the Ark of the Covenant there, and later it is where Solomon builds the temple, and his own palace. From then on Jerusalem is the center of worship of the Israelitish church. It is the place where the Lord was presented in the temple as a baby, where He tarried to talk to the priests at age twelve, where He cleansed the temple, had the last supper, was crucified and then rose. It is a central place in both the old and new Testaments. The city was built on Mount Zion, the highest point of the mountains of Judea. A city, in the Word, represents doctrine, the organized knowledge of the truths of the church. Mountains represent love of the Lord and the consequent worship. If you put those things together, Jerusalem on Mount Zion signifies the doctrine of love to the Lord, and how it governs your life. This is why David was led to make Jerusalem the most important city of the land, and why all worship was conducted there. And this is also why Jeroboam was condemned for introducing idol worship in Samaria. In the Book of Revelation, John's vision of the city New Jerusalem descending from God is a prophecy of a new dispensation of doctrine coming from the Lord.

322. The four animals and the four and twenty elders fell down before the Lamb, signifies the acknowledgment and consequent glorification of the Lord by the angels of the higher heavens. This is evident from the signification of "the four animals and the four and twenty elders," as being, in general, the whole heaven, but especially the inmost heaven, consequently the angels of the higher heavens (of which see above, n. 313; here especially the angels of those heavens, because in what follows there is glorification by the angels of the lower heavens. Also from the signification of "fell down before the Lamb," as being acknowledgment from a humble heart. That "to fall down" signifies humiliation, and in that state acknowledgment of heart, see above n. 290. Acknowledgment of the Lord's Divine Human is clearly meant, for that is signified by "the Lamb" (See above, n. 314). What the higher heavens are, and what the lower heavens are, shall be told in a few words. There are three heavens: the third or inmost heaven is where the angels are who are in celestial love; the second or middle heaven is where the angels are who are in spiritual love; the first or ultimate heaven is where the angels are who are in spiritual-natural love. The third or inmost heaven is conjoined with the second or middle by intermediate angels, who are called celestial-spiritual and spiritual-celestial angels; these intermediate angels, together with the angels of the third or inmost heaven, constitute the higher heavens; while the remainder of those in the second or middle heaven, together with those who are in the first or outmost heaven, constitute the lower heavens. The "four animals" signify specifically the third or inmost heaven, and the "four and twenty elders" the second or middle heaven that is in conjunction with the third or inmost; thus together they signify the higher heavens. Respecting the intermediate angels, called celestial-spiritual and spiritual-celestial, and the conjunction of the third heaven with the second by these, see Arcana Coelestia 1577, 1824, 2184, 4047, 4286, 4585, 4592, 4594, 6435, 6526, 8787, 8802, 9671).
