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.

166. Verse 23. And her sons I will kill with death, signifies that thus falsities are extinguished. This is evident from the signification of "sons," as being truths of the church from the Word, and, in the contrary sense, falsities (of which presently); also from the signification of "king with death," as being to extinguish; for falsities are separated, and as it were extinguished by temptations, and by man's refraining from them, and shunning them, and holding them in aversion. "Sons" in the Word signify truths, and in the contrary sense falsities, because the spiritual sense of the Word treats only of such things as relate to the church and heaven; and all things of the church and of heaven have reference to the goods which are of love, and to the truths which are of faith. From this it is that the names of kinships and relationships, as husband, wife, son, daughter, brother, sister, daughter-in-law, son-in-law, and others, signify spiritual things that have reference to spiritual birth, which is regeneration, and to the heavenly marriage, which is the marriage of good and truth. The things that are born of this marriage are likewise goods and truths. From this it is that "daughters" in the Word signify goods, and "sons" truths, both derived from the good that is signified by "father," and from the truth that is signified by "mother." (That all the truths and goods that are with the regenerate man are conjoined according to spiritual relationships, and follow in order, see Arcana Coelestia 2508, 3815, 4121. That all who are in heaven are also associated according to spiritual relationships, see in the work on Heaven and Hell 205. That "sons" signify truths and the affections of truth, is shown in Arcana Coelestia 489, 491, 533, 2623, 3373, 4257, 8649, 9807; that "sons of sons" signify truths in successive order, n. 6583, 6584; that by "father," "mother," "brethren," "children," goods and truths, or evils and falsities with man are signified, n. Arcana Coelestia 10490; that "to smite the mother upon the sons," is to destroy all things of the church, n. 4257; that the Lord called Himself "the Son of man," because He was Divine truth, and because every truth of heaven and of the church proceeds from Him, see above, n. 63.)
