The answer is: 2 and a half

Deut 3:12-13

When diving into the historical significance of the tribes occupying land east of the Jordan River, it’s fascinating to see how deeply the geographic and tribal divisions shaped ancient Israelite identity. The two and a half tribes — Reuben, Gad, and a half-tribe of Manasseh — settled in this area for its lush pastures, even though the bulk of Israel's population crossed the Jordan to conquer Canaan.

If we look back at Deuteronomy 3:12-13, it’s not just about land; it symbolizes personal choices. Imagine leaving the Promised Land’s central inheritance behind, a bold decision motivated by the needs of their herds rather than divine promises. They made a pact with Moses, which stresses compromise and recognizing the various needs within a community.

Moreover, you might find it interesting that the eastern tribal lands served as a buffer zone between ancient Israel and the nomadic tribes of the nearby desert territories. This strategic positioning allowed for an interaction that colored both Israel’s military and economic strategies.

These tribes faced significant battles, and their choices often posed hard questions about loyalty and faithfulness to the collective community. Their story is more than real estate; it's a deep narrative about finding one’s place. Such dynamic history resonates with all of us, who at times navigate individual desires alongside communal responsibilities.
