'The Twelve' in the Bible

And the names of the twelve sent are these: first, Simon, called Peter, and Andrew his brother; James, he of Zebedee and John his brother;

And Jesus said to them, Verily I say to you, That ye having followed me, in the regeneration when the Son of man should sit upon the throne of his glory, shall be seated ye also upon twelve thrones, judging the twelve tribes of Israel.

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

Then one of the twelve having gone forth, he being called Judas Iscariot, to the chief priests,

And it being evening, he reclined at table with the twelve.

And he yet speaking, behold, Judas, one of the twelve, came, and with him a great crowd, with swords, and sticks, from the chief priests, and the more ancient of the people.
