2943. 'To all entering into the gate of his city, saying' means matters of doctrine through which one comes to faith. This is clear from the meaning of 'a gate' as a place of entry and so as that which, in the same way as a door, leads in, dealt with in 2145, 2152, 2356, 2385, and from the meaning of 'a city' as truth, which constitutes faith, dealt with in 402, 2268, 2449, 2451, 2712. In the Ancient Church a city was not like the city of later or of modern times. That is to say, a city did not consist of a collection or gathering together of individuals but of separate families living side by side. A family descended from the same forefather constituted a city. The city of Nahor, for example, to which Abraham's servant went to betroth Rebekah to Isaac, Genesis 24:10, consisted of the family of Nahor which was there. And Shalem, the city of Shechem, to which Jacob came after his departure from Paddan Aram, Genesis 33:18 and the whole of Chapter 34, consisted of the family of Hamor and Shechem which was there. And the same was so with all other cities in those times.

[2] And as it had come down to them from the most ancient people that nations and families represented heavenly communities, and so the things of love and charity, 685, 1159, therefore when a city is mentioned instead of a family, and a people instead of a nation, truth that constitutes faith is meant. It is also why in the genuine sense the city of God and the holy city mean faith in the Lord. And as 'a city' meant faith, 'the gate of the city' means matters of doctrine through which one comes to faith. The same was also meant in the Jewish representative Church by the judges and elders sitting in the gate of the city and giving judgement there, as is evident from historical sections of the Word, and also in Zechariah,

These are the things that you shall do: Speak the truth, everyone to his companion; judge in your gates the truth and the judgement of peace. Zechariah 8:16.

And in Amos,

Hate evil, and love good, and establish judgement in the gate. Amos 5:15.

'A gate' also means the place of entry into the rational mind, and the rational mind is compared to a city, see 2851.

10229. 'And you shall take the silver of expiations from the children of Israel' means the purifying truths springing from good that are the Church's. This is clear from the meaning of 'the silver' as truth springing from good, dealt with in 1551, 2954, 5658, 6112, 6914, 6917, 8932; from the meaning of 'expiations' as purification from evils, dealt with above in 10218, so that 'the silver of expiations' is truth that purifies; and from the representation of 'the children of Israel' as the Church, dealt with in the places referred to in 9340. The words 'truth that purifies' are used because all purification from evils is effected by means of truths, see 2799, 5954, 7044, 7918, 9089. The implications of all this are that by himself a person thinks nothing but evil; for by himself he does not think about God nor about good and just behaviour towards his neighbour, unless it is to his own advantage. Nor indeed does he think about heaven and eternal life, only about the world and life there. As long as this is a person's state of mind his thought springs from what is below him and not from what is above him, thus from hell and not from heaven. To think what is good therefore a person's thought must spring from heaven, so that his mind must be raised in that direction. This is accomplished solely by means of truths such as exist within the Church, derived from the Word; for those truths teach about the nature of God, who the neighbour is, the existence of heaven, the reality of eternal life, and in particular what evil and good are. When these truths pass into the mind its inner levels are raised above the self, and are accordingly drawn away from those things below the self, thus away from evils. From this it may be recognized that all purification or removal from evils is effected by means of truths, which are therefore called purifying truths.
