'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)

(Referencat: Luke 10)

8937. 'Your flocks and your herds' means forms of good, internal and external. This is clear from the meaning of 'flocks' as internal forms of good, and from the meaning of 'herds' as external forms of good, both dealt with in 2566, 5913. The reason why 'flocks' means internal forms of good is that to flocks belong lambs, sheep, kids, she-goats, rams, and he-goats, and these mean such things as are forms of innocence and forms of celestial and spiritual love in the internal man. And the reason why 'herds' means external forms of good is that to herds belong oxen, young oxen, and calves, and these mean such things as are forms of good and truth in the external man. For what was meant by 'oxen', see 2180, 2566, 2781; 'young oxen' and 'calves', 1824, 2830; 'lambs', 3519, 3994, 7840; 'sheep', 4169; 'kids' and 'she-goats', 3519, 4005, 4006, 4871; 'rams', 2830, 4170; and he-goats', 4169 (end), 4769.
