Jerusalem
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.

Arcana Coelestia #1672
1672. 'And the kings who were with him' means the apparent truth that goes with that good. This is clear from the meaning of 'kings' in the Word. Kings, kingdoms, and peoples in the historical and prophetical sections of the Word mean truths and the things that belong to truths, as may be confirmed from many places. In the Word a careful distinction is made between people and nation, 'people' meaning truths, 'nation' goods, as shown already in 1259, 1260. Kings have reference to peoples, and not so much to nations. The children of Israel, before they sought to have kings, were 'a nation' and represented good, or that which is celestial; but after they desired a king and received one, they became 'a people' and represented not good or that which is celestial, but truth or that which is spiritual, and this was the reason why this was ascribed to them as a fault in 1 Samuel 8:7-end. This, in the Lord's Divine mercy, will be explained elsewhere. In the present verse, since 'Chedorlaomer' is referred to, and then the phrase 'the kings who were with him' is added, both good and truth are meant - good by 'Chedorlaomer' and truth by 'the kings'. But what kind of good and truth it was when the Lord's temptations first began has been stated above.
