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.

9913. 'And its hole for the head shall be in the middle of it' means the course which the inflow from the higher source takes. This is clear from the meaning of 'the robe's hole for the head in the middle of it' as the place where the inflow enters from the higher, or what amounts to the same thing, more internal source, thus from the celestial kingdom into the spiritual kingdom; for the external good of the celestial kingdom flows into the internal good of the spiritual kingdom, see immediately above in 9912. The reason why the 'robe's hole for the head in the middle of it' has this meaning is that the spiritual kingdom, in particular the inward part of it, is meant by 'the robe', 9825, and the inflow, communication, and joining of celestial things to spiritual ones by the neck where the robe's 'hole for the head' was, 3542, 5320, 5328. For the head on a person corresponds to the Lord's celestial kingdom, and the body to His spiritual kingdom, so that the neck in between, which the robe's hole for the head encircles and clothes, corresponds to the mediation or inflowing of the celestial kingdom into the spiritual kingdom.

[2] That such things are meant by 'the robe's hole for the head in the middle of it' may seem to be absurd, altogether so to those who know nothing about heaven, or about spirits and angels there, and consequently know nothing about correspondence. The existence of a correspondence of all aspects of the human being with all things in heaven has been shown at the ends of a number of chapters, see the places referred to in 9280. In general the head corresponds to celestial things, the body to spiritual things, and the feet to natural things, 4938, 4939. From this it is evident that 'the neck' by virtue of its correspondence means the inflow, communication, and joining of celestial things to spiritual things. Therefore 'the robe's hole for the head', which was made to go round the neck, means the course which that inflow takes; for Aaron's garments represented in general those things that belong to the Lord's spiritual kingdom, 9814. From this it is evident that the reference in this verse to the hole or part of the robe that goes round the neck describes the actual inflowing. Furthermore it should be remembered that angels and spirits appear wearing garments, and that each one of their garments is representative, as everyone in heaven knows. So it is that each one of Aaron's garments too is representative of such things as exist in the heavens. For the Word from the Lord has been written in such a way that everything there even to the smallest detail has a correspondence with heavenly things, and in such a way that it is a means serving to join things together. The reason why the member of the Church does not know about all this, even though he has such a Word, is that he has turned his interiors round to the world, so far round that he cannot be raised towards heaven and learn about it, see 9706, 9707, 9709.
