A foreshadowing mystery: Why did Joshua have the elect remain 2000 cubits behind him when they crossed over...?

the Jordan River into the Promised Land. Suppose that Joshua was a similitude of Jesus, and the Hebrews are the Bride of Christ, and the Promised Land represents the Kingdom of Heaven. What does it mean to cross the water before entering and for their leader to go first 2000 cubits ahead of them? Furthermore, who do the two spies sent into Jericho represent? What does Jericho represent? Who does Rahab the harlot represent? And her scarlet thread in the window of her house? Why did they blow trumpets for seven days, and why blow the trumpet seven times on the morning of the seventh day before the wall fell? What does the wall represent? And why was Jericho destroyed by fire? So many believers confess to be spiritually minded and no so very little about spiritual things. Solve my mystery.
