'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)

(Odkazy: Luke 10)

8354. 'And Jehovah showed him [some] wood' means that the Lord instilled good. This is clear from the meaning of 'showing' - when done by 'Jehovah', that is, the Lord - as imparting perception, which because it takes place through influx means instilling it; and from the meaning of 'wood' as good, dealt with in 643, 2784, 2812, 3720.
