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.

73. And out of His mouth a sharp two-edged sword going forth, signifies the dispersion of falsities by the Word. This is evident from the signification of "going forth out of the mouth," as being, in reference to the Lord, Divine truth, thus the Word, for the Word goes forth out of the Lord's mouth. This is evident also from the signification of "the long sword," or the "sword," as being truth combating; and as truth, when it combats, disperses falsities, therefore a "long sword" also signifies the dispersion of falsities. The long sword is called "two-edged and sharp," because truth completely disperses. (That "long sword" or "sword" signifies truth combating against falsities and destroying them, see Arcana Coelestia 2799, 6353, 8294.) As "the long sword" is frequently mentioned in the following pages (as in chap. 2:12, 16; 6:4, 8; 13:10, 14; 19:15, 21), passages from the Word illustrating and showing that it signifies truth combating and dispersing falsities, will here be omitted. This will be illustrated and shown in those places.
