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.

4303. 'Therefore the children of Israel do not eat the sinew of that which was displaced, which is on the hollow of the thigh' means that no truths containing falsities were assimilated. This is clear from the meaning of 'eating' as being joined to and made one's own, dealt with in 2187, 2343, 3168, 3513, 3596, 3832, and from the meaning of 'the sinew' as truth, for truths within good are like sinews within the flesh, and truths are also meant in the spiritual sense by 'sinews' and good by 'flesh', 3579, 3813. 'Sinews' and 'flesh' have a similar meaning in Ezekiel,

Thus said the Lord Jehovih to these bones, I will lay sinews upon you and cover you with flesh, and I will put spirit within you I looked, and behold, there were sinews upon them, and flesh came up. Ezekiel 37:6, 8.

Here the new creation of man, that is, the regeneration of him, is the subject. But once truths have been distorted they cease to be truths any longer; and the more they are distorted into the reverse of truths the nearer they get to falsities. This is why 'the sinew of that which was displaced' means falsity. For 'the hollow of the thigh' means the point where conjugial love is joined to natural good, and therefore the point where the influx of spiritual truth into natural good takes place, see 4277, 4280. From this it is evident that 'therefore the children of Israel do not eat the sinew of that which was displaced, which is on the hollow of the thigh' means that no truths containing falsities were assimilated. The reason why these things are said concerning the children of Israel is that 'Israel' means the Divine celestial-spiritual, 4286, while 'children' or 'sons' means truths, 489, 491, 2623. So the meaning is that the truths belonging to the Divine celestial-spiritual did not assimilate any falsities as part of themselves.
