Augustine of Hippo, on Matt 19:27

“Then Peter answering, said to him: Behold we have left all things, and have followed thee: what therefore shall we have?”

“(de Civ. Dei, xx. 5.) The same holds good, by reason of this number twelve, of those that are to be judged. For when it is said, Judging the twelve tribes, yet is not the tribe of Levi, which is the thirteenth, to be exempt from being judged by them; nor shall they judge this nation alone, and not also other nations.”
