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.

2145. 'He was sitting at the tent door' means the holiness which existed with Him at that time, namely the holiness of love, which is meant by 'as the day was getting warmer', dealt with in what follows next. This is clear from the meaning of 'a tent' as holiness, dealt with in 414, 1102, 1566. And for the reason why 'tents' meant forms of holiness, see the same paragraphs. Since the Lord at this time had the perception meant by the oak-groves of Mamre, which is a lower rational perception, yet more interior than that meant by the oak-grove of Moreh, dealt with in 1442, 1443, it is here represented and so is meant by his sitting at the tent door, that is, at the entrance to holiness. As regards perceptions being more interior or less interior, this may be illustrated from the perceptions which the most ancient people had. From these people I have heard that the more they were immersed in mere facts acquired from the objects of hearing and sight the lower their perceptions became; but the more they were raised up from them towards the celestial things of charity and love the more interior these perceptions became, as they were then closer to the Lord.
