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.

2148. That 'he lifted up his eyes' means that He saw within Himself is clear from the meaning of 'lifting up the eyes'. By 'eyes' in the Word is meant interior sight, or the understanding, as becomes clear from the places quoted in 212, and therefore by 'lifting up the eyes' is meant seeing and perceiving the things which exist above oneself. Things that are interior are expressed in the Word by those that are higher, as in the expressions 'looking upwards', 'lifting up the eyes to heaven', and 'thinking high things' - the reason being that man imagines heaven to be on high, or up above himself, though in fact it is not on high but exists in things that are internal; when the heavenly things of love are present in a person, his heaven exists within him, see 450. From this it is plain that 'lifting up the eyes' means seeing within oneself.
