32:21 And every shock-fighter among you crosses the Yarden
Moshe was willing to accept the request of Reuven and Gad to settle on the east of the Yarden River only after they promised to help fight to inherit the Land of Israel. We learn a powerful lesson of responsibility from this story. While they already possess the land that was going to be their home, these tribes are not allowed to settle down until every other tribe in Israel also has land of their own in which to settle. Life in Eretz Yisrael demands and engenders the concept that everyone is responsible for his fellow. This spirit of collective cooperation can be seen in the Kibbutz movement formed by the original Zionist pioneers. These unique farms, known as Kibbutzim, took collective responsibility so far that members didn’t even own their own clothing or personal property. Everything was shared equally among the members.
