Arcana Coelestia # 3055
3055. 'Outside and away from the city' means removed from matters of doctrine. This is clear from the meaning of 'the city' as doctrine, dealt with in 402, 2449, from which it is evident that 'outside the city' means outside of, thus removed from, matters of doctrine.
3055a 'Near a well of water' means to receive the truths of faith. This is clear from the meaning of 'a well of water' as the Word, the source of the truth of faith, and also truth itself, dealt with in 2702. The phrase 'a well of water' is used in this verse, but 'a spring' in all that follows; and for the difference between the two in the internal sense - between 'a well of water' and 'a spring' see the paragraph just referred to.
Feet
Our feet are the lowest parts of our bodies, and they're very useful! In the Bible, feet represent the lowest and most utilitarian part of our spiritual selves -- the “natural” level. This everyday aspect of life is involved with routine tasks and demands and the thoughts associated with them. It's not terribly deep or introspective, but it is useful -- just like feet. This correspondence is true of the Lord and of church communities, too. The Lord's Divine Natural leads us through relatively simple obedience (think of the Ten Commandments). Churches, too, have a natural level on which they serve their communities in simple but tangible ways.
