Midrash su Deuteronomio 12:14

3) Until here (Vayikra 17:5) Scripture speaks of consecrations which were dedicated at the time that bamoth (temporary altars) were interdicted and he offered them outside (instead of within), their punishment being stated (to be kareth). Where is the exhortation against this? In (Devarim 12:13) "Take heed unto yourselves lest you offer up your burnt-offerings in every place that you see. (Devarim 12:14) "but in the place, etc."

One verse (Devarim 12:14) states (that the Temple is to be built) "in (the portion of) one of your tribes," and, another (here) "of all your tribes." How are these two verses to be reconciled? Israel knew that the Temple was destined to be built in the portion of one of them — wherefore they set aside the "fat land" of Jericho. Who ate of it all of these years (until its building)? The descendants of Keini (Yithro), the father-in-law of Moses, ate of it four hundred and forty years. But with the building of the Temple, they left, viz. (Judges 1:16) "And the children of the Keini, the father-in-law of Moses went up from the city of palms (Jericho)." These are the words of R. Shimon. R. Yehudah says: They went to Yabetz, viz. ( Chronicles 2:55) "and the families of scribes, who dwelt in Yabetz … These were the Keinites, etc."
