TSK · Joshua 21:8

the Gadites and the Reubenites came and addressed Moses, Eleazar the priest, and the leaders of the community. They said,

Thus they will have towns in which to live, and their grazing lands will be for their cattle, for their possessions, and for all their animals.

So the Israelites assigned these cities and their grazing areas to the Levites from their own holdings, as the LORD had instructed.

A toss of a coin ends disputes, and settles the issue between strong opponents.
