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.

In Genesis 11:4, this signifies the worship of self, which consists of a person exalting himself above others, even to the point of worship. This is why self-love, which is arrogance and pride, is called 'height,' 'loftiness,' and 'lifting up,' and is described with anything high. Self-love in worship, or the worship of self is called 'a tower,' because 'a city' signifies doctrine, and ancient cities were fortified with towers with guards. Towers were also built on the borders of a country. This is why they were called guard towers, or watchmen in 2 Kings 9:17, 17:9, 18:8, and watch-towers, in Isaiah 23:13.

In Matthew 21:33; Isaiah 5:2, this signifies interior truths into which there is influx, and communication with heaven. (Arcana Coelestia 918[4])

In Psalm 48:12, this signifies to consider the higher or interior things of that church. (Arcana Coelestia 453[10])

'To build a tower,' as in Luke 14:27, signifies acquiring interior truths.
