'Jericho' generally signifies the good of truths.

In Luke 10:30, this signifies the church in possession of the knowledges of truth and good.

In Joshua 6:1, 'Jericho' signifies instruction and the good of life because no one can be instructed in the truths of doctrine but he who is in the good of life. In an opposite sense, it signifies the profanation of truth and good. (Apocalypse Explained 700)

(Reference: Luke 10)

If you think about sitting, it seems fair to say that where you're sitting is more important than that you're sitting. Sitting in a movie theater, sitting in a classroom, sitting in the driver's seat of a car, sitting in the defendant's seat at a trial, sitting at the family dinner table -- those are very, very different things. But even so, the fact that you're sitting in those places is important -- it means you are part of what's going on, you're staying in place. This is similar to "sitting" in the Bible. Sitting on a throne indicates judgment; sitting in a tent door indicates holiness. The context is crucial. But in all cases "sitting" indicates a sense of permanence, belonging, and full participation in the spiritual state illustrated through the context.
