'Jericho' generally signifies the good of truths.

In Luke 10:30, this signifies the church in possession of the knowledges of truth and good.

In Joshua 6:1, 'Jericho' signifies instruction and the good of life because no one can be instructed in the truths of doctrine but he who is in the good of life. In an opposite sense, it signifies the profanation of truth and good. (Apocalypse Explained 700)

(Odkazy: Luke 10)

10335. 'And I, behold, I have appointed with him Aholiab the son of Ahisamach, belonging to the tribe of Dan' means those in whom the good and truth of faith are present, among whom the Church is to be established. This is clear from the representation of 'Aholiab' as those in whom the good and truth of faith are present. The reason why these are represented by Aholiab is that he was from the tribe of Dan, and that tribe means those in whom the good and truth of faith are present, see 3923, 6396. And the reason why these two - Bezalel from the tribe of Judah, and Aholiab from the tribe of Dan - were chosen to carry out the work, by which Divine celestial and spiritual realities would be represented, was that by Bezalel all those in whom the good of love is present should be understood, and by Aholiab all those in whom the good and truth of faith are present. Thus those who are in the inmost parts of heaven and the Church should be understood by Bezalel, and those who are in the last and lowest parts of them by Aholiab. And when they who are inmost and those who are last and lowest are referred to by name, all who are within the whole of heaven and within the whole of the Church should be understood. For this matter, see above in 10329; and when reference is made to what is first and what is last all things should be understood, 10044.

[2] The tribe of Judah was also in reality the first of the tribes, and the tribe of Dan the last of them. The fact that the tribe of Judah was in reality the first of the tribes is clear from father Israel's blessing of his sons in Genesis 49, where Reuben, Simeon, and Levi, who were the firstborn, are cursed, and Judah is blessed. See regarding Reuben there, verses 3, 4; regarding Simeon and Levi, verses 5-7; and regarding Judah, verses 8-12. And the fact that Dan was the last of the tribes, see 1710, 3923, 6396. The inmost heaven furthermore is inhabited by those in whom the good of love to the Lord exists, and the lowest by those in whom the truth of faith springing from good is present. The expression 'in whom the truth of faith springing from good is present' is used because the truth of faith is not the truth of faith present in a person unless it springs from good; for truth is born from good. Therefore unless good resides within truth there is no soul and so no life within it. Those in whom the truths of faith springing from good are present inhabit the lowest parts of heaven, but not those in whom the truths of faith are devoid of good; the latter do not inhabit heaven. Since the truth of faith acts as a servant to the good of love, as what is last does to what is first, it says of Aholiab that Jehovah appointed him to be with Bezalel, that is, to be his assistant; and of Bezalel it says that Jehovah filled him with the spirit of God in wisdom, and in intelligence, and in knowledge, and in all [manner of] work, verse 3.
