And Jesus said to them, Truly I say to you that you who have followed Me, in the regeneration, when the Son of Man shall sit in the throne of His glory, you also shall sit on twelve thrones, judging the twelve tribes of Israel.

And going up to Jerusalem, Jesus took the twelve disciples apart in the way, and said to them,

Then one of the twelve, called Judas Iscariot, went to the chief priests.

And when evening had come, He sat down with the Twelve.

And as He was yet speaking, behold, Judas came, one of the Twelve. And with him came a great crowd with swords and clubs, being sent from the chief priests and elders of the people.
