Numbers 32-34, Psalm 58

Israel has just defeated Midian and they entire community is getting ready to cross the Jordan into the Promised Land and begin their military campaign against the inhabitants of the land. When the tribes of Reuben, Gad, and the half tribe of Manassah, see that the land of the Midianites is good for cattle, they ask if they can settle there. Moses wrongly assumes that they are trying to avoid going to war with their brothers, opting instead to settle outside of the Promised Land and break rank from the others. By the end of the conversation, they cut a deal with Moses, assuring him that they, too, will go to war with the rest of Israel before coming back to settle in the land.
