Joshua 5 - Through the 40 years of wandering in the wilderness the people of Israel never took the time to circumcise all the male citizens. So, in the land of Canaan they fulfilled that requirement. This was a significant way for them to remove all the ties to their old life for now they were to embark on their new adventure of living a life of victory in their new home. Joshua would be introduced to the One who would lead the way: the Commander of the Lord's army!
Joshua 6 - This chapter presents the conquest of Jericho and the beginning of Israel's march of victory as they would take hold of the Promised Land as their own. Discipline and patience were hallmarks of Joshua's method of military leadership. He required the people to march around the city once a day for six days, and then still be quiet as they marched six more times on the seventh day. Only on the seventh time around they were permitted to shout and watch the walls of Jericho crumble. They would go in and claim the city and destroy its inhabitants.
Joshua 7 - God had made clear that the people of Israel were not to lay claim to any of the spoils for their own. It was a way for God to impress on Israel that they were to dedicate the "first fruits" of their spoil to the Lord. Giving Him first was and still is the appropriate manner for our giving. Achan disobeyed and he brought disaster on himself and his family as a result.
Joshua 8 - If only Achan had waited! When Israel conquered Ai God allowed them to take the spoils of victory as their own! Israel would use the tactic of flight and subtlety to conquer this city. Joshua would keep his hand raised as long as it took for the Israelites to complete the fight. Afterwards Joshua read the all the words of the Law to remind Israel who they worshiped and their obligation to obey their God.
