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.

1321. That 'let us confound their lip' means that nobody has the truth of doctrine becomes clear from the meaning of 'lip' as doctrine, dealt with above at verse 1. Consequently 'confounding lips' is confounding the things that comprise doctrine, that is, the truths of doctrine. In the internal sense 'confounding' means not only darkening but also erasing and scattering so that no truth is left. When worship of self supplants worship of the Lord all truth is not only perverted but also done away with, till at length falsity is acknowledged in place of truth and evil in place of good. In fact all the light of truth comes from the Lord, and all thick darkness from man. When man takes the Lord's place in worship the light of truth turns to thick darkness, and in this case people see the light as thick darkness, and thick darkness as the light.

[2] Such also is the life of those people after death. To them the life of falsity looks like light, while the life of truth looks to them like thick darkness. But when they go near heaven the light of such life turns to total darkness. While they are in the world they are indeed able to utter the truth, and to do so eloquently and with seeming zeal. And because they are all the time thinking of themselves it seems to them as though truth is also in their minds. But because their end in view is worship of themselves, this end conditions their thoughts so that they do not acknowledge truth except insofar as self is present in that truth. Anyone like this, though truth is on his lips, clearly has no truth within him. This is quite evident in the next life, for there such people not only fail to acknowledge the truth which they have professed during their lifetime, but also hate it and persecute it. This they do to the extent that pride or worship of self is not taken away from them.
