ARE relatively uncontaminated..as if mixing them would contaminate them? Poor choice of words.

I suppose you're right.

I could have said unmixed.

But from the perspective of God in the Old Testament--and perhaps in the New given the 144,000--12,000 from each tribe--evidently HE has SOME investment in keeping the tribal identity somewhat pure . . . for whatever reason(s) we may not have much of a clue about at present--other than that it appears to please His taste, priorities, passions. I vote with HIM.
