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.

344. Then I saw another angel ascending from the rising of the sun. (7:2) This symbolizes the Lord providing and moderating.

The angel here means the Lord in respect to Divine love, because he ascended from the rising of the sun, and from the rising of the sun or from the east means from Divine love. For in the spiritual world the Lord is the sun and the east, and He is called that in respect to that love. His providing and moderating is apparent from His commandment to the four angels not to harm the earth and sea till the servants of God had been sealed on their foreheads.

That in the highest sense an angel means the Lord's Divine humanity is apparent from the following verses:

...the Angel of (Jehovah's) presence delivered them because of His love and His clemency. He redeemed them, and took them up, and carried them all the days of eternity. (Isaiah 63:9)

The Angel who has redeemed me from all evil, bless (them). (Genesis 48:16)

The Lord, whom you seek, will suddenly come to His temple, even the Angel of the covenant, whom you are desiring. (Malachi 3:1)

...I send an Angel before you to keep you in the way... Beware of his presence...; for My name is in the midst of him. (Exodus 23:20-23)

"Angel" and "one sent" are, in Hebrew, the same word. That is why the Lord so often calls Himself one sent by the Father, meaning by it His Divine humanity.

In a relative sense, on the other hand, an angel is anyone who accepts the Lord, whether in heaven or in the world.
