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.

5293. 'And let them gather all the food' means all things that have a useful purpose. This is clear from the meaning of 'gathering' as drawing together and preserving; and from the meaning of 'food' as things which have a useful purpose. In the internal sense 'food' means, strictly speaking, those things which nourish a person's soul, that is, which nourish him when his bodily life is ended. For when this is ended his soul or spirit is living, and he no longer needs material food as he did in the world; but he does need spiritual food, which consists in everything that has a useful purpose and everything leading to this. That which leads to what has a useful purpose is knowing what goodness and truth are; and that which has such a purpose is the desire to realize these in actions. These are the things with which angels are nourished and which are therefore called spiritual and celestial foods. A person's mind - the place within him where his will and understanding, that is, his intentions or ends in view, reside - is nourished by no other kind of food, even while he lives in the body. Material food does not extend as far as that; it extends only to his bodily parts, which are sustained by that material food to the end that the mind may be sustained by food for the mind while the body is sustained by food for the body, that is, to the end that there may be a healthy mind in a healthy body.

[2] The reason 'food' in the spiritual sense means everything that has a useful purpose is that a person's entire knowledge, his entire understanding and wisdom, and so his entire will must have a useful purpose as its end in view. Consequently as is the nature of the purpose he has in view, so is the nature of his life. The truth that 'food' in the spiritual sense means everything with a useful purpose is evident from the following words spoken by the Lord,

Jesus said to the disciples, I have food to eat of which you do not know. The disciples said to one another, Has anyone brought Him anything to eat? Jesus said to them, My food is to do the will of Him who sent Me, and to accomplish His work. John 4:32-34.

And elsewhere,

Do not labour for the food which perishes, but for the food which endures to eternal life, which the Son of Man will give you. On Him the Father - God - has set His seal. John 6:27.
