5344. 'Which was round about it he laid up in the midst of it' means that what existed first in the exterior natural was stored away by it in the interior parts of the interior natural. This is clear from the meaning of 'round about' as things on the outside and so in the exterior natural; and from the meaning of 'the midst' as things on the inside, dealt with in 1074, 2940, 2973, and so in the interior natural. The reason 'in the midst of it (the city)' means in the interior parts of the interior natural is that 'a city' means the interior parts, 5297, 5342. The interior parts of the interior natural are those parts in it which are called spiritual ones, and the spiritual parts in it are those parts which belong to the light of heaven and are therefore able to shed light on the parts there which belong to the light of the world, which strictly speaking are called natural ones. It is in the spiritual parts of the interior natural that the truths linked to good have been stored away.

[2] Those spiritual parts there are what correspond to the angelic communities in the second heaven, and a person is in communication with this heaven through his remnants. This heaven is the one that is opened when a person is being regenerated, and it is the one that is shut when a person does not allow himself to be regenerated. For remnants - that is, truths and forms of good stored away in interior parts - are nothing else than correspondences with the communities belonging to that heaven.

5297. 'Food in the cities' means such things present in the interior parts of the natural mind. This is clear from the meaning of 'food' as all things that have a useful purpose, dealt with just above in 5293; and from the meaning of 'cities' as the interior parts of the natural mind. In the universal sense 'cities' means matters of doctrine known to the Church, see 402, 2268, 2449, 2451, 2712, 2943, 3216, 4491, 4493, but in a particular sense it means the interior parts of a person where matters of doctrine exist, or rather where truths joined to good exist. For the forms of truth and good existing with a person form a city so to speak, see 3584, which is why a person who has the Church within him is called 'the city of God'. The meaning that 'a city' has is similar to the meaning that 'a house' has. In a universal sense 'a house' means good; in a particular sense however it means a person, 3128, and in a specific sense it means his mind so far as goodness and truth are joined together there, 3538, 4973, 5023. Also a house with its rooms, surrounding buildings, and courtyards is a city in miniature.

[2] The interior parts of the natural mind are meant by 'cities' in Isaiah,

On that day there will be five cities in the land of Egypt which speak in the lips of Canaan and swear to Jehovah Zebaoth. Isaiah 19:18.

Both forms of good and of truth present in the interior parts are meant by 'cities' in the Lord's parable in Luke,

He said to the one who used his mina to earn ten minas, Well done, good servant; because you have been faithful over a little, be over ten cities. And he said to the second who earned five minas, You also, be over five cities. Luke 19:11 and following verses.

The recommendation here therefore that they should store up food in cities and should guard it means that truths joined to good were to be stored away in the interior parts of the natural mind. When these truths and forms of good have been stored away there they are called remnants. These remnants are where a person's actual spiritual life resides, and they are what a person is nourished by spiritually whenever need and desire, that is, whenever spiritual famine, arises.
