Arcana Coelestia #3622
3622. 'Like these of the daughters of the land' means because they are not from that ground, that is, from truths which the genuine Church knows. This is clear from the meaning of 'the daughters of the land' as Churches, for 'the daughters' means affections for good and truth, 2363, and 'the land' means the region where the Church is situated, and so means the Church itself, dealt with in 662, 1066, 1067, 1262, 1733, 1850, 2117, 2118 (end), 2928, 3355. 'The daughters of the land' accordingly means the goods and truths of the Church.
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.
