'The Twelve' in the Bible

Jesus, therefore, said unto the twelve - Are, ye also, wishing to withdraw?

Jesus answered them - Did not, I, make choice, of you, the twelve? And yet, from among you, one, is, an adversary.

Now he was speaking of Judas, son of Simon Iscariot: for, the same, was about to deliver him up, - one of the twelve.

But, Thomas, one of the twelve, the one called Didymus, was not with them when Jesus came.
