Arcana Coelestia # 3083
3083. 'And filled her pitcher' means vessels for receiving. This is clear from the meaning of 'a pitcher' in the internal sense, since it is a vessel able to receive water, as a recipient of cognitions of truth, also of truth itself, which are meant by 'water'. For 'water' in the internal sense means cognitions, and also truth, see 28, 680, 2702, 3058.
Sparrow and swallow
In Psalm 84:3, 'a sparrow' signifies spiritual truth, and 'a swallow' signifies natural truth from which worship is performed.
