The tribes of Reuben and Gad had very large herds. Seeing that Jazer and Gilead were good cattle land, they came to Moses, Eleazar, and the leaders and asked to receive that land as their holding, without crossing the Jordan.
Moses challenged them: “Are your brothers to go to war while you stay here?” He reminded them how earlier scouts had discouraged Israel, and how God made the people wander forty years.
Reuben and Gad answered with a promise. They would build sheepfolds and fortified towns for their children, but their fighters would go first, in the vanguard. They used the Hebrew word chalutzim, meaning “armed pioneers,” because they would march ahead until the land was subdued.
Moses agreed on the condition that they truly cross over and fight. If they did, Gilead would be theirs; if not, they would receive land in Canaan. Moses also assigned them, and the half-tribe of Manasseh, the lands of Sihon and Og. They rebuilt and renamed towns, and families of Manasseh captured and settled more places in Gilead and beyond.
