2788. That 'on the third day' means that which has been completed, and the beginning of sanctification, is clear from the meaning of 'the third day'. 'Day' in the Word means state, 23, 487, 488, 493, 893, as also does 'year', and as in general do all periods of time - an hour, day, week, month, year, or age; also morning, midday, evening, and night; and spring, summer, autumn, and winter. And when 'the third' is added to any of these the end of that state, and at the same time the beginning of the next, are meant. Here, the subject being the sanctification of the Lord which was effected by means of temptations, 'the third day' means that which has been completed and at the same time the beginning of sanctification, as also follows from what has been said previously to this. The reason for this meaning is that when He had fulfilled everything the Lord was to rise again on the third day, for the things that were done by the Lord while He lived in the world, that is, the things that were yet to be done by Him, were embodied within the representatives of the Church as though they had already been done. This was as it is with the internal sense of the Word, for with God that which is yet to come to pass and that which already is are one and the same; indeed to Him the whole of eternity is here and now.
Arcana Coelestia 487-488)
 This is why the number three was representative not only in the Ancient Church and in the Jewish but also among various gentile nations; see what has been stated about this number in Arcana Coelestia 720, 901, 1825. That such was the origin of the meaning of 'three' is clear in Hosea,
We will return to Jehovah, for He has wounded and will heal us; He has stricken and will bind us up; He will revive us after two days, on the third day He will raise us up that we may live before Him. Hosea 6:1-2.
Here 'the third day' stands for the coming of the Lord and His resurrection. The same is clear from Jonah, in that he was in the stomach of the fish three days and three nights, Jonah 1:17, to which the Lord refers in Matthew as follows,
As Jonah was in the belly of the whale three days and three nights, so will the Son of Man be three days and three nights in the heart of the earth. Matthew 12:40.
 It should be realized that in the internal sense of the Word 'three days' and 'the third day' have the same meaning, as also do 'three' and 'third' in the following places: In John,
Jesus said to the Jews, Destroy this temple and in three days I will raise it up. He was speaking of the temple of His body. John 2:19-21; Matthew 26:61; Mark 14:58; 15:29.
It is a well known fact that the Lord rose again on the third day.
 For the same reason the Lord also distinguished three periods in His life: in Luke,
Go and tell that fox, Behold, I cast out demons and perform cures today and tomorrow, but on the third day I reach completion. Luke 13:32.
Also, the Lord underwent the final temptation, which was that of the Cross, at the third hour of the day, Mark 15:25. Three hours later, that is, at the sixth hour, darkness fell over the whole land, 1
Luke 23:44. And three hours after that, at the ninth hour, the end came, Mark 15:33-34, 37. But in the morning of the third day He rose again, Mark 16:1-4; Luke 24:7. See also Matthew 16:21; 17:22-23; 20:18-19; Mark 8:31; 9:31; 10:33-34; Luke 18:33; 24:46. From all this, and especially from the Lord's resurrection on the third day, the number three was representative and possessed a spiritual meaning. This fact becomes clear from the following places in the Word:
When Jehovah came down upon Mount Sinai He told Moses that he was to sanctify the people today and tomorrow and they were to wash their garments and be ready on the third day, for on the third day Jehovah would come down. Exodus 19:10-11, 15-16.

 The flesh of a sacrifice made as a vow-offering or as a freewill-offering was to be eaten on the first and the second day; nothing was to be kept until the third day but was to be burned, because it was an abomination. So too with the flesh of a sacrifice made as a 'eucharistic' offering; if this was eaten on the third day the one offering the sacrifice would not be accepted and that soul would bear his iniquity. Leviticus 7:16-18; 19:6-7.
Anyone who touched a dead body was to purify himself on the third day, and on the seventh day he would be clean. If he did not do so that soul would be cut off from Israel. And one that was clean was to sprinkle water over the unclean person on the third day and on the seventh day. Numbers 19:12-13, 19.
Those who had killed someone in battle and had touched one who had been slain were to purify themselves on the third day and on the seventh day. Numbers 31:19.

 Just as a group of three and a third one were representative, so also was a third part, as in the following:
