If you could get all the people in an organization rowing in the same direction, you could dominate any industry, in any market, against any competition, at any time.

-Patrick Lencioni

 Now this is why he did so: All those who came out of Egypt—all the men of military age—died in the desert on the way after leaving Egypt.  All the people that came out had been circumcised, but all the people born in the desert during the journey from Egypt had not.

Joshua 5:4-5

Now Jericho was tightly shut up because of the Israelites. No one went out and no one came in. 

Joshua 6:1

 March around the city once with all the armed men. Do this for six days.  Have seven priests carry trumpets of rams’ horns in front of the ark. On the seventh day, march around the city seven times, with the priests blowing the trumpets. When you hear them sound a long blast on the trumpets, have all the people give a loud shout; then the wall of the city will collapse and the people will go up, every man straight in. 

Joshua 6:3-5

 In other battles, Israelites were sometimes permitted to take spoils. Jericho was different. God wanted Israel to recognize that this victory and its spoils belonged to Him, rather than treating the conquest as an opportunity for personal enrichment.

Now Joshua sent men from Jericho to Ai, which is near Beth Aven to the east of Bethel, and told them, “Go up and spy out the region.” So the men went up and spied out Ai.

When they returned to Joshua, they said, “Not all the people will have to go up against Ai. Send two or three thousand men to take it and do not weary all the people, for only a few men are there.” So about three thousand men went up; but they were routed by the men of Ai, who killed about thirty-six of them. They chased the Israelites from the city gate as far as the stone quarries and struck them down on the slopes. At this the hearts of the people melted and became like water.

Joshua 7:2-5

 Stand firm in one spirit, contending as one man for the faith of the gospel.

Philippians 1:27
