'Tribes' in the Bible

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

And then shall appear the sign of the Son of man in heaven; and then shall all the tribes of the land lament, and they shall see the Son of man coming on the clouds of heaven with power and great glory.
