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.

213. 'Knowing that they were naked' means knowing and acknowledging that they did not dwell in innocence, as they had done previously, but were under the influence of evil. This is clear from the final verse of the previous chapter, where it is said, 'And they were both naked, the man and his wife, and they were not ashamed'. There it may be seen that being naked and not ashamed means being innocent. The contrary is meant when they are ashamed, as in this chapter which says that they sewed fig leaves together and hid themselves. Indeed when innocence is lacking nakedness arouses feelings of shame and disgrace because people are made aware of their own evil thoughts. Consequently nakedness in the Word stands for evil and shame and has reference to a corrupted Church, as in Ezekiel,

She was naked and bare, and was downtrodden in her own blood. Ezekiel 16:7, 11.

In the same prophet,

Let them leave her naked and bare, and let her nakedness be uncovered. Ezekiel 23:29.

In John,

I counsel you to buy white garments to clothe you, and let not the shame of your nakedness be manifested. Revelation 3:18.

And in reference to Judgement Day,

Blessed is he who is awake and keeps his garments, so that he may not walk naked, and men see his shame. Revelation 16:15.

In Deuteronomy,

If a man has found in his wife some nakedness, let him write her a bill of divorce. Deuteronomy 24:1.

This also was why Aaron and his sons were commanded to have linen breeches to cover their naked flesh when they approached the altar to serve, lest they should bring iniquity upon themselves and die, Exodus 28:42-43.
