'The Twelve' in the Bible

So Jesus said to the twelve, Have you a desire to go away?

Then Jesus said, Did I not make a selection of you, the twelve, and one of you is a son of the Evil One?

He was talking of Judas, the son of Simon Iscariot. It was he who was to be false to Jesus--one of the twelve.

Now Thomas, one of the twelve, named Didymus, was not with them when Jesus came.
