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.
Under
In the Bible, things that are lower down, or under, physically, generally represent things that are lower or more external spiritually. In some cases, the lower things have been separated and put away to protect the good, but in others, it can mean that a less exalted idea or good desire is supporting a more exalted one.
