Yahweh Lies to Joshua (Chapter 3) - Chapter 3 is very similar in wording to the last chapters.  Yahweh once again promises Joshua, and Joshua reports in 3:10, "He (Yahweh, or God) will without fail drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites"

In essence, this is a lie that will become obvious a few chapters later in the book. 

There is one miracle that occurs where the Israelites were able to cross the Jordan River without getting their feet wet.  This occurred during their march toward Jericho.

The Israelite priests holding the Ark of the Covenant to lead the column, until they got to the Jordan River.  the Israelites would then have to stand 2,000 cubits behind the ark, and make sure they had been properly cleaned prior to their march, etc.  As the water receded the priests holding the Ark stood in what was once the middle of the river, while the Israelites continued to the other side of the bank.
