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.

1198. 'From whom they came forth' means that cognitions, as these exist with them, are facts. This is clear from what has been stated. These are not said to have been 'begotten' by those who belonged to Egypt but to have 'gone forth', for they are not such as use natural and factual knowledge to reason about spiritual and celestial things and in so doing fabricate for themselves doctrinal teachings, as do those described before. Instead they learn cognitions of faith from another source, but have no other end in view to knowing and retaining these in the memory than they have with other things in which they have no interest beyond merely knowing them, and only then for the reason that by so knowing they may be promoted to positions of importance, and for other like reasons. So different is knowledge of cognitions of faith from knowledge of natural things that the two have scarcely anything in common. This explains why they are not said to have been 'bore' but to have 'gone forth' from them. Such being the character of 'Philistines' they inevitably pervert cognitions of faith by means of reasonings from them, and as a consequence fabricate false doctrines for themselves. They belong therefore among those who are barely able to be regenerated and to receive charity, both because they are uncircumcised at heart and because the false assumptions and consequently the life of their understanding hinder and prevent.
