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.

29. And the Prince of the kings of the earth, signifies from whom is all the truth from good in the church. This is evident from the signification of "Prince of kings," as meaning from whom is all truth; a "prince" denoting what is primary, and "kings" truths; and, because it refers to the Lord, who is here called "Prince of kings," it means from whom is all truth (that "prince" means what is primary, see Arcana Coelestia 1482, 2089, 5044; and that "kings" are truths, see in the explanation of the following verse, where it is said, "and hath made us kings and priests," n. 31; also from the signification of the "earth," as meaning the church (of which in what follows). One who knows not the internal sense of the Word must needs believe that the kings of the whole earth are here meant; whereas kings are not meant, nor earth; but by "kings" are meant all who are in truths from good; and by the "earth" is meant the church. (That by the "earth" is signified the church is shown in many places in the Arcana Coelestia, from which these particulars may be seen: That by the "earth" is signified the kingdom of the Lord and the church, n. 662, 1066, 1068, 1262, 1413, 2928, 3355, 4447, 4535, 5577, 8011, 9325, 9643. The chief reason of which is, that by the "earth" is meant the land of Canaan; and the church was there from most ancient times, n. 567, 3686, 4447, 4454, 4516, 4517, 5136, 6516, 9325, 9327; also that, in the spiritual sense, by the "earth" is meant the nation who dwell thereon, and their worship, n . 1262. That the "new heaven the new earth" signify the church in the heavens on earth 1733, 1850, 2117, 2118, 3355, 4535, 10373. That by the creation of heaven and earth, in the first chapters of Genesis, in the internal sense, is described the establishment of the Most Ancient Church, see n. 8891, 9942, 10545. That to "create" is to establish and regenerate, see n. Arcana Coelestia 10373. That "ground," too, signifies the church; "ground" from the reception of seeds, which are truths, but "earth" from the nations therein, and their worship, see n. 566, 1068, 10570. Moreover, "earth," as it signifies the church, signifies also the religious principle, consequently also such as is idolatrous; as the land of Egypt, the land of the Philistines, the land of Chaldea, and of Babel, and many others. That "earth" signifies the church is also briefly shown in the small work on The Last Judgment 3, 4.)
