'The Twelve' in the Bible

Now these are the names of the twelve apostles: first Simon who is called Peter, and Andrew his brother, James the [son] of Zebedee, and John his brother,

And Jesus said to them, "Truly I say to you that in the renewal [of the world], when the Son of Man sits on his glorious throne, you who have followed me--you also will sit on twelve thrones judging the twelve tribes of Israel.

And [as] Jesus was going up to Jerusalem, he took the twelve disciples by themselves and said to them on the way,

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

And [when it] was evening, he was reclining at table with the twelve disciples.

And [while] he was still speaking, behold, Judas--one of the twelve--arrived, and with him a large crowd with swords and clubs, from the chief priests and elders of the people.
