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.

613. That 'members of his own generation' has to do with faith is not evident from the sense of the letter, which sense is historical. Nevertheless because they are matters of a purely internal nature here, things that have to do with faith are meant. It is also clear from the train of thought that 'generations' here means nothing else. The same occurs several times in the Word, as in Isaiah,

Let those that be of you build the waste places of old; raise up the foundations of generation upon generation, and you will be called, The repairer of the breach, The restorer of paths to dwell in. Isaiah 58:12.

All the details here mean things that have to do with faith. 'The waste places of old' means those on the celestial side of faith, 'the foundations of generation upon generation' at the same time meaning those on the spiritual side, and which had lapsed since ancient times. In the same prophet,

They will build up the waste places of old, they will raise up the former desolations, and they will renew the waste cities, the desolations of generation upon generation. Isaiah 61:4.

Here the meaning is similar. In the same prophet,

They will not labour in vain, and they will not generate in sudden terror; for they will be the seed of the blessed of Jehovah, and their offspring with them. Isaiah 65:23.

Here also 'generating' has reference to things that have to do with faith, and 'labouring' to those that have to do with love. 'The seed of the blessed of Jehovah' has reference to the latter, 'offspring' to the former.
