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.

589. Verse 21. And repented not of their murders, signifies who have not actually turned themselves away from extinguishing the things that pertain to the understanding of truth, the will of good, and spiritual life therefrom. This is evident from the signification of "repenting," as being actually turning oneself away (as above, n. 585; and from the signification of "murders," as being the extinction of the understanding of truth, of the will of good, and of spiritual life therefrom; for "man" signifies the understanding of truth, and wisdom (See above, n. 280, 546, 547); and "to kill" signifies to extinguish spiritual life by the falsities of evil (See above, n. 315, 547, 572). That "murder or manslaughter" signifies the extinction of spiritual life can be seen without proof passages from the Word, from this, that the particulars here must be understood spiritually, and "to kill" spiritually is to extinguish spiritual life, which is done by the falsities of evil.

[2] This is why the devil is called "a murderer from the beginning" by the Lord, in John:

Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and stood not in the truth, because there is no truth in him. When he speaketh a lie he speaketh from his own, for he is a liar and the father thereof (John 8:44).

This means the Jewish nation itself, which through its idolatries and traditions extinguished spiritual life by the falsities of evil; "the father thereof" means their fathers; because they extinguished spiritual life by the falsities of evils it is said, "there is no truth in him; when he speaketh a lie, he speaketh from his own, for he is a liar, and "the father thereof," a "lie" signifying in the Word the falsity of evil.

[3] "Murders" and a "lie" have a similar signification in the following words in Revelation:

Without shall stand the dogs, and the sorcerers, and the whoremongers, and the murderers, and the idolaters, and everyone that loveth and maketh a lie (Revelation 22:15).

Because those who are meant by "Babylon" extinguish all Divine truths by the falsities of evil, Babylon is called:

An abominable shoot, a garment of those that are slain, of those thrust through with the sword; for thou hast destroyed thy land, thou hast slain thy people (Isaiah 14:19, 20).

This is said of Babylon. Those are said to be "thrust through with the sword" who have been destroyed by the falsities of evil; "to destroy the land" signifies to destroy the church; and "to slay the people" signifies to extinguish the truths of the church.
