Three
The number three in the Bible represents completeness. That's why Jesus rose on the third day after the Crucifixion -- his transformation was complete. It's why Elijah stretched himself on the dead child three times, why Jonah was in the belly of the fish for three days, why the Lord called Samuel three times, and many more. It's also reflected in the fact that there are three levels of heaven, three levels of hell, three levels to human life and, ultimately, three aspects of the Lord Himself: Father, Son and Holy Spirit.
Arcana Coelestia # 10234
10234. 'And Jehovah spoke to Moses, saying' means perception as a result of enlightenment from the Lord through the Word. This is clear from the meaning of 'Jehovah speaking to Moses' as enlightenment from the Lord through the Word, dealt with in 10215; and from the meaning of 'saying' as perception, dealt with in 2862, 3509, 5743, 8660. It should be remembered that when some new matter, distinct from what has gone before, is to be presented the words Jehovah spoke to Moses are used, as at verses 11, 17, 22, 34 of the present chapter, and also elsewhere. The new matter that is being presented now has regard to purification from evils and falsities.
