54. On the Lord's day, signifies Divine influx then. This is evident from the signification of "the Lord's day," as being then the Lord is instructing man, thus when He is flowing in. The Lord's day is the day of the Sabbath, and the Sabbath in the ancient churches, which were representative churches, was the most holy thing of worship, because it signified the union of the Divine and the Human in the Lord, and thence also the conjunction of His Divine Human with heaven (See Arcana Coelestia 8494-8495, 10356, 10360, 10370, 10374, 10668). But when the Lord had united His Divine with His Human that holy representative ceased, and that day became a day of instruction (n. 10360). For this reason revelation was made to John on the Lord's day. Revelation here is instruction concerning the state of the church.

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.
