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.

259. The existence of writings in the heavens is a provision of the Lord for the sake of the Word; for the Word in its essence is Divine truth, and from it is all heavenly wisdom, both with men and with angels; for the Word was dictated by the Lord, and what is dictated by the Lord passes through all the heavens in order and terminates with man. Thereby it is adapted both to the wisdom of angels and the intelligence of men. Thereby, too, the angels have a Word, and read it the same as men do on the earth, and also draw from it their doctrinals, and preach from it (221). It is the same Word; but its natural sense, which is the sense of the letter with us, does not exist in heaven, but only the spiritual sense, which is its internal sense. What this sense is can be seen in the small treatise on The White Horse spoken of in the Apocalypse.
