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.

1709. 'Three hundred and eighteen men' means the nature of those goods, that is to say, they are the holy things employed in conflict. The number eighteen entails this, as also does the number three hundred, for these numbers are compounded from three and six. Three means that which is holy, as shown in 720, 901, and six means conflict, as shown in 737, 900. Abram's bringing out of such a number of men is true historically; but still it was also representative, as is every historical detail of the Word recorded in the five Books of Moses, and in the Books of Joshua, Judges, Samuel, Kings, Daniel, and Jonah, where in like manner numbers embody arcana within them. For nothing has been written in the Word that was not of such a representative nature. If it were not representative it would not be the Word and it would never have been recorded that Abram brought out three hundred and eighteen, and also that they were trained and were born in his house, besides many other details mentioned in this chapter.
