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.

1864. That 'on that day Jehovah made a covenant with Abram' means the joining together of the Lord's Interior Man and His Internal Man is clear from the meaning of 'a covenant' as a joining together, dealt with already in 665, 666, 1023, 1038. Here, because in the internal sense the Lord is the subject, it means an interior conjunction. For the Lord advanced more and more towards conjunction and union with Jehovah His Father, till at length He became one, that is, the Human Essence itself also became Jehovah, who was the Lord's Internal itself. These things were represented by 'the covenant which Jehovah made with Abram'. Anyone may see that Jehovah never makes a covenant with man, for such would be contrary to the Divine. What is man but something base and filthy, which of itself thinks and does nothing but evil? All the good that he does comes from Jehovah. From this it becomes clear that this covenant, like every other covenant made with Abram's descendants, was nothing else than a representative of the Divine and of the heavenly things of the kingdom of God. This particular covenant made with Abram was a representative of the joining together of the Lord's Human Essence and His Divine Essence, that is, Jehovah. That it was a representative of the joining together of the Lord's Interior Man and His Internal Man, that is, Jehovah, is clear from what has gone before - that the Lord joined and united Himself more and more through the conflicts brought about by temptations and through victories. What the Interior Man was has been stated already, namely that which was between the Internal and the External.
