664. Verse 11. And after the three days and a half, signifies when it is finished, thus the end of the old church and the beginning of the New Church. This is evident from the signification of "the three days and a half," as being fullness and completion as to the end of the old church, when there is the beginning of the New Church (See above, n. 658). It is said "after the three days and a half" because in the Word "days" signify states, here the last state of the church; for in the Word all times, as "hours," "days," "weeks," "months," "years," "ages," signify states, as here the last state of the church, when there is no longer any good of love or truth of faith left. Because "days" signify states, and the establishment of the Most Ancient Church is treated of in the first chapter of Genesis, and it becomes established successively from one state to another, it is there said:

That there was evening and there was morning the first day, the second, the third, the fourth, the fifth, and the sixth days, even to the seventh, when it was finished (Genesis 1:5, 8, 13, 19, 23, 31; 2:2);

and the "days" there do not mean days, but the successive states of the regeneration of men at that time, and the consequent establishment of the church with them. So also elsewhere in the Word.

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.
