'The Twelve' in the Bible

Now the names of the twelve Apostles were these: first, Simon called Peter, and his brother Andrew; James the son of Zabdi, and his brother John;

"I solemnly tell you," replied Jesus, "that in the New Creation, when the Son of Man has taken His seat on His glorious throne, all of you who have followed me shall also sit on twelve thrones and judge the twelve tribes of Israel.

Jesus was now going up to Jerusalem, and He took the twelve disciples aside by themselves, and on the way He said to them,

At that time one of the Twelve, the one called Judas Iscariot, went to the High Priests

When evening came, He was at table with the twelve disciples,

He had scarcely finished speaking when Judas came--one of the Twelve--accompanied by a great crowd of men armed with swords and bludgeons, sent by the High Priests and Elders of the People.
