'Tribes of Israel' in the Bible

Jesus said to them, "Truly I tell you, [since] you have become my followers, in the time of new beginnings [i.e., the church age], when the Son of man sits on His glorious throne, you apostles will also sit on twelve thrones, judging [i.e., through their writings] the twelve tribes of Israel [i.e., God's people].

so you can eat and drink at my table in my [coming] kingdom. [Also] you will sit on [twelve] thrones [See Matt. 19:28], judging the twelve tribes of Israel [i.e., judging God's people through their writings].
