'The Twelve' in the Bible

Then said Jesus unto the twelve, Will ye also go away?

Jesus answered them, Did not I choose you the twelve, and one of you is a devil?

He spake of Judas Iscariot the son of Simon: for he it was that should betray him, being one of the twelve.

Then said Judas (the Iscariot, one of the Twelve--the one who afterwards betrayed Jesus)

Now he said this, not because he cared about the poor [for he had never cared about them], but because he was a thief; and since he had the money box [serving as treasurer for the twelve disciples], he used to pilfer what was put into it.

"I am not talking about all of you; for I know the ones I have chosen [i.e., which of the twelve apostles would be faithful]. But let the Scripture [Psa. 41:9] be fulfilled [that says], 'The person who eats with me has [viciously] turned against me.'

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