'The Twelve' in the Bible

Jesus, therefore, said to the twelve, "Do ye also wish to go away?"

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

But He was speaking of Judas, son of Simon Iscariot; for he was about to betray Him, being one of the twelve.

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