Initially, Joshua represents truth from the Bible fighting against evil, assisting Moses. Joshua then takes on this complete representation when Moses dies. When a person decides to leave behind what is merely natural and looks for something deeper, that person might find something he didn't expect. His or her mind is populated by selfish loves that don't want to think internally about heavenly love. Though the person can subdue these, he or she must fight to do what's right, and finds that they are never fully conquered so as to be absolutely gone. Joshua continues to represent the truths from the Bible that we know and that we use to fight against the evils in ourselves. All the wars in the Bible represent this same battle.

In Exodus 17:9, he signifies fighting truth. (Arcana Coelestia 8595)

In Exodus 32:17, he later signifies the truth of the Word surveying and observing. (Arcana Coelestia 10454)

220. 'His voice going to and fro' means that only a residue of perception was left, so small as to be solitary and inaudible, so to speak. This is also clear from the next verse in which it is said that Jehovah called out to the man. A similar usage occurs in Isaiah,

The voice of one crying in the wilderness; the voice said, Cry! Isaiah 40:3, 6.

'Wilderness' stands for a Church where no faith exists; 'the voice of one crying stands for the declaration of the Lord's coming, in general for every declaration of His coming, as is made to regenerate persons who have this dictate residing in them.
