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)

(Референце: Exodus 17; Matthew 10, Matthew 10:35, Matthew 10:36)

219. 'Jehovah God's voice going to and fro in the garden' means a dictate which filled them with fear. This becomes clear from the meaning of 'voice' in the Word where 'Jehovah's voice' stands for the Word itself, for the doctrine of faith, for conscience, which is inward mindfulness, and also for every expression of disapproval resulting from these. This also is why thunderbolts are called 'Jehovah's voices', as in John,

Then the angel called out with a loud voice, like a lion roaring; and when he called out seven thunders sounded their voices. Revelation 10:3-4.

This stands for the voice at that time being both external and internal. In the same book,

In the days of the voice of the seventh angel the mystery of God was fulfilled. Revelation 10:7.

Here the meaning is similar. In David,

Sing to God, make melody to the Lord who rides above the heavens of heavens of old. Behold, He will put forth His voice, a mighty voice. Psalms 68:32-33.

'The heavens of heavens of old' stands for the wisdom of the Most Ancient Church. 'Voice' stands for revelation and also for an inner dictate. In the same author, The voice of Jehovah is upon the waters; the voice of Jehovah is powerful; the voice of Jehovah is glorious; the voice of Jehovah breaks the cedars; the voice of Jehovah flashes forth flames of fire; the voice of Jehovah causes the wilderness to shake; the voice of Jehovah causes the hinds to calve, and strips the forests bare. Psalms 29:3-5, 7-9.

And in Isaiah,

Jehovah will cause the excellence of His voice to be heard, for Asshur will be dismayed by the voice of Jehovah. Isaiah 30:30-31.
