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.
Midst
The "midst" of something in the Bible represents the thing that is most central and most important to the spiritual state being described, the motivation that drives everything else. In general this will be something we love or feel, because at the core of things we are what we love; our loves define us.
