'The Twelve' in the Bible

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

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

And, when about to go up to Jerusalem, Jesus took with Him the twelve disciples privately, and on the way He said to them,

Then one of the twelve, the one called Judas Iscariot, going to the high priests,

And, evening coming on, He was reclining at table with the twelve;

And, while He is yet speaking, behold, Judas, one of the twelve, came, and with him a large multitude, with swords and clubs, from the high priests and elders of the people.
