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.

3404. 'Isaac sowed in that land' means interior truths from the Lord as they appear to the rational. This is clear from the meaning of 'sowing' in the highest sense as Divine Truth from the Lord who is the Sower, 3038, and in the internal sense as the truth and good residing with a person, which stem from that Divine Truth, 3373; and from the meaning of 'land' as rational concepts which, when enlightened from the Divine, are appearances of truth, 3368, or what amounts to the same, are interior truths from the Lord as they appear to the rational. These appearances or truths belong on a higher degree, for as far as verse 14 it is these that are the subject in the internal sense. These appearances of truth are the kind that exist with angels, and are such as go immeasurably above anyone's understanding as long as he lives in the world.

[2] To make it clearer still what appearances of truth are, let the following example be added: It is well known that the Divine is infinite as regards Being (Esse) and eternal as regards Manifestation (Existere), and that what is finite is incapable of comprehending what is infinite, or indeed of comprehending what is eternal, since what is eternal is the Manifestation (Existere) of what is infinite. And because the Divine itself is infinite and eternal, so are all things which proceed from the Divine infinite and also eternal. And as those things are infinite angels are quite incapable of grasping them, for they too are finite beings. That being so, things that are infinite and eternal present themselves to angels within appearances that are finite, though within appearances such as are very far above the range of what man can comprehend. For example, man is quite incapable of possessing any idea of what is eternal except from what is temporal. And being incapable of having any idea other than this he is incapable of comprehending what 'from eternity' is and so what the Divine prior to the existence of time or creation of the world is. And as long as his thinking contains any idea at all that is formed from what is temporal, he slips inevitably, if he thinks about what is eternal, into errors from which he cannot be rescued. But the angels, whose ideas are not formed from anything temporal but from timeless state, are enabled to perceive it supremely well, for to them eternity is not eternity of time but eternity of state devoid of any idea of that which is temporal.

[3] From this one may see what the appearances existing with angels are like compared with man's, and how superior their appearances are to man's. For man cannot have one shred of thought, not even the least shred, that is not in some way temporal and spatial in origin, whereas angels' thought has no such origin at all. Instead their thought has its origin in timeless state, in which the being (esse) and the manifestation (existere) of things is the only consideration. These few comments show the nature of the appearances of truth which are the subject in these verses, and that these appearances belong to a higher degree. The verses that follow deal in order with the appearances of truth that belong to a lower degree which are also suitable to the human race.
