Arcana Coelestia #5106
5106. 'And Joseph said to them' means the celestial of the natural. This is clear from the representation of 'Joseph' as the celestial of the natural, dealt with above in 5086.
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.
