'Judging' in the Bible

And Jesus said unto them, Verily I say unto you, that ye who have followed me, in the regeneration when the Son of man shall sit on the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel.

that ye may eat and drink at my table in my kingdom; and ye shall sit on thrones judging the twelve tribes of Israel.

For what have I to do with judging them that are without? Do not ye judge them that are within?
