'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)

As with many common verbs, the meaning of “to say” in the Bible is highly dependent on context. Who is speaking? Who is hearing? What is it about? Is it a command, a message, an apology, instruction? All these things enter into the meaning of “say.” In general, though, “saying” has to do with sharing truth at various levels -- from the most exalted power people can have to perceive the Lord's desires directly to the most basic of orders issued to people at their lowest.
