Arcana Coelestia #220
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.
Arcana Coelestia #9888
9888. 'Before the face of it' means to eternity. This is clear from the meaning of 'before the face' as to eternity; for 'the breastplate' means heaven and every good and truth that constitutes it, 9879. What is 'before the face' in heaven is in the Lord's everlasting sight, thus is preserved to eternity.
