In Zechariah 2:4, this signifies the church of people who will receive the Divine proceeding of the Lord on a deep level within themselves. (Apocalypse Explained 629[6])

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.
