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.

(Odkazy: Arcana Coelestia 2838 [1-4], Genesis 47:26)

260. A little paper was at one time sent to me from heaven, on which there were a few words only written in Hebrew letters, and I was told that every letter involved arcana of wisdom, and that these arcana were contained in the inflections and curvatures of the letters, and thus also in the sounds. This made clear to me what is signified by these words of the Lord:

Verily I say unto you, until heaven and earth pass away, one iota or one tittle shall not pass away from the law (Matthew 5:18).

That the Word in every tittle of it is Divine is known in the church; but just where the Divine lies hid in every tittle has not been known heretofore, and therefore shall be told. In the inmost heaven the writing consists of various inflected and circumflected forms, and the inflections and circumflections are in accordance with the forms of heaven. By means of these angels express the arcana of their wisdom, and also many things that they are unable to express in spoken words; and what is wonderful, the angels know this writing without training or a teacher, it being implanted in them like their speech (see 236); therefore this writing is heavenly writing. It is implanted because all extension of thoughts and affections and consequent communication of intelligence and wisdom of the angels proceeds in accordance with the form of heaven (201); and for the same reason their writing flows into that form. I have been told that the most ancient people on this earth, before letters were invented, had such writing; and that it was transferred into the letters of the Hebrew language, and these letters in ancient times were all inflected, and none of them, as at present, were bounded by straight lines. Thus it is that in the Word Divine things and arcana of heaven are contained even in its iotas, points and tittles.
