862. That 'it happened at the end of forty days' means the duration of the former state, and the beginning of the one that followed, is clear from the meaning of 'forty', see 730, where, the subject being temptation, the phrase 'forty days and forty nights' was used, which meant the duration of temptation. Here, since the subject is the state following temptation, 'forty days' is mentioned but not forty nights. The reason is that charity now starts to appear, which in the Word is compared to the day and is called the day. Faith however which precedes but has not yet been so joined to charity is compared to the night and is called the night, as in Genesis 1:16, and elsewhere in the Word. Faith is also called 'the night' in the Word because it receives its light from charity, just as the moon does from the sun. Faith is therefore also compared to the moon and is called the moon; and love or charity is compared to the sun and is called the sun. 'Forty days', or the duration of time meant by them, refers both to the things that precede and to those that follow; hence the statement 'at the end of forty days', which accordingly means both the duration of the previous state, and the beginning of the one being described now. This then begins the description of the second state following temptation of the member of this Church.

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.
