In Genesis 19:37; 21:26; 30:32; 40:7; Matthew 6:30; Luke 12:28, this signifies the perpetuity and eternity of a state. (Arcana Coelestia 2838)

In Psalm 2:7, this signifies in time; for with Jehovah the future is present. (True Christian Religion 101)

The expression 'even to this day' or 'today' sometimes appears in the Word, as in Genesis 19:37-38, 22:14, 26:33, 32:32, 35:20, and 47:26. In a historical sense, these expressions have respect to the time when Moses lived, but in an internal sense, 'this day' and 'today' signify the perpetuity and eternity of a state. 'Day' denotes state, and likewise 'today,' which is the current time. Anything related to time in the world is eternal in heaven, and to represent this, 'today' or 'to this day' is added. Although, in the historical sense, this appears as if the expressions only have a literal meaning, just like it says in other parts of the Word, such as Joshua 4:9, 6:25, 7:20, Judges 1:21, 26, etc. 'Today' means something perpetual and eternal in Psalms 2:7, 119:89-91, Jeremiah 1:5, 10, 18, Deuteronomy 29:9-14, Numbers 28:3, 23, Daniel 8:13, 11:31, 12:11, Exodus 16:4, 19, 20, 23, John 6:31, 32, 49, 50, 58, Matthew 6:11, and Luke 11:3.

615. And like the voice of loud thunder. This symbolizes the Lord speaking through the new heaven out of Divine love.

Lightnings, thunderings and voices symbolize enlightenment, perception and instruction, as may be seen in no. 236. And seven thunders speaking symbolize the Lord's speaking through the whole of heaven (no. 472).

When the Lord speaks through heaven, He does so from the third heaven through the second heaven, thus from love through Divine wisdom, for the third heaven is impelled by His Divine love, and the second heaven by His Divine wisdom. The Lord never speaks in any other way when He speaks from the higher heavens. This, then, is what is meant by a voice like the voice of many waters, and by a voice like the voice of loud thunder. Many waters are the Divine truths of Divine wisdom, and loud thunder is the Divine goodness of Divine love.
