574. And I heard the number of them.- This signifies their quality perceived, as is evident from the signification of hearing, as denoting to perceive (see above, n. 14, 529); and from the signification of number, as denoting the quality of the thing treated of, concerning which, see above (n. 429); here, the quality of the falsities of evil that conspire against the truths of good, from which and on behalf of which are the reasonings of the sensual man, which are signified by the number of the armies of the horsemen, spoken of just above. But the quality of these is further described in the next verse in these words: "And thus I saw the horses in the vision, and them that sat on them, having breast-plates fiery, and purple, and sulphurous; and the heads of the horses as the heads of lions; and out of their mouths went forth fire, smoke, and brimstone." These words are expressive of the quality that is here signified by number. Some reference to number appears to be meant here by number, but in the spiritual world numbers do not exist, for spaces and times there are not measured and determined by numbers, as in the natural world, therefore all numbers, in the Word, signify things, and the number itself signifies the quality of the thing treated of, see above (n. 203, 336, 429, 430); and in Heaven and Hell 263).

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.
