6670. 'And in all [manner of] service in the field' means the aim to bring things of the Church under their control. This is clear from the meaning of 'service' as the aim to bring under their control, dealt with above in 6666; and from the meaning of 'the field' as the Church, dealt within 2971, 3766.

3765. 'Behold, a well' means the Word. This is clear from the meaning of 'a well' as the Word and also as doctrine drawn from the Word, dealt with in 2702, 3096, 3424. The Word is called 'a well' here because the subject is the natural, which by itself can do no more than understand the literal sense of the Word. But the Word is called 'a spring' when the subject is the rational, by which one is able to see the internal sense of the Word.
