The answer is: 2 and a half

Deut 3:12-13

In the book of Deuteronomy, specifically chapters 3:12-13, we learn that two and a half tribes—the tribes of Reuben, Gad, and half of the tribe of Manasseh—received their inheritance on the east side of the Jordan River. This geographical layout not only highlights the strategic decisions made by these tribes but also reflects their unique contributions to the larger narrative of Israelite identity.

It's interesting to note that these tribes wanted settled land suitable for their cattle rather than crossing into Canaan. Their desire shows the practical considerations based on their needs rather than a simple quest for conquest. The names Reuben and Gad echo through history as symbolizing division; Echoing themes pertinent to community, belonging, and identity remains apparent, as these tribes maintained a connection to the broader nation of Israel while choosing partial separation.

The invitation to the tribes to assist their fellow Israelites, as they crossed over to battle in Canaan, reveals a call to unity. Even though they chose their comfort and security, they carried with them the responsibility to support their kin.

Moreover, this story provides fertile ground for discussions about choices and commitments. When tribes take ownership of their territories, they’re also embracing a shared destiny with the larger group. This invites reflection on how we can balance personal desires with the collective needs of our communities today.
