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.

3167. 'And to [her] mother' means to natural truth also, that is to say, spiritual things passed from the rational to it, even as they passed to natural good, dealt with just above. This is clear from the meaning of 'a mother' as the Church, which by virtue of truth is called 'a mother', dealt with in 289, 2717. So that people may know how spiritual things pass to natural good and to natural truth as a result of truth being introduced into good in the rational, a brief description must be given here. Everyone has an internal and an external, his internal being called the internal man, and his external the external man. But few know what the internal man is and what the external. The internal man is one and the same as the spiritual man, and the external man one and the same as the natural man. The spiritual man depends for understanding and wisdom on things that belong to the light of heaven, whereas the natural depends for its understanding and wisdom on things that belong to the light of the world. Regarding those two kinds of light, see 3138. For in heaven none but spiritual things exist, whereas in the world none but natural exist. The human being was created in such a way that in him spiritual things and natural things, that is, his spiritual man and his natural man, should accord with each other or make one. But in that case the spiritual man ought to have control over the things in the natural, and the natural man ought to obey, like a servant his master.

[2] Through the Fall however the natural man started to raise itself above the spiritual man and so turn Divine order itself upside down. As a consequence the natural man separated itself from the spiritual, and spiritual things could not reach it any longer except so to speak through chinks to provide the ability to think and speak. But so that spiritual things might flow in once more into the natural man this had to be regenerated by the Lord, that is, truth from the natural man had to be introduced and joined to good in the rational. When this happens spiritual things have access to the natural man, for now the light of heaven flows in and illuminates things in the natural man, and causes what is there to receive light. The goods there receive the warmth that the light conveys, which is love and charity, whereas the truth receives rays of light, which is faith. It is in this way that spiritual things pass from the rational into natural good and truth. Natural good in that case consists in all the delight and satisfaction gained from having service to the spiritual man as the end in view, and so service to the neighbour, more so to one's country, more so still to the Lord's kingdom, and above all to the Lord. And natural truth consists in all doctrinal teaching and factual knowledge which have wisdom, that is, the performance of those things, as the end in view.
