Curiosity from Genesis

In Israel's last declarations to his sons Simeon and Levi are condemned for their anger and violence and told that they will be dispersed, albeit in the family. And the Simeon tribe seems not to have had a clear territory separable from that of Judah. The Levite tribe was, of course, scattered through the whole of Israel.

I don't see "founder effect" -- the subsequent trajectories of the two tribes was quite different despite Israel's joint curse. But it's a curious note.
