Joshua chapter 3 tells us that Joshua along with the nation of Israel crossed the flood swollen river of Jordan. These people had a one major goal in their mind. To capture the city of Jericho (a militarily important target) which will prepare the way to conquer the promise land. There was a challenge however. The current of the Jordan is very swift at Jericho. Besides it was the harvest season and the melting snows in the Lebanon mountains caused the river to overflow.
