'Twelve Apostles' in the Bible

Therefore, Jesus said to the twelve apostles, "Do you not want to go [with me] either?"

Now He spake of Judas Iscariot, the son of Simon; for he was about to betray Him, though he was one of the twelve apostles.

"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 one of the twelve apostles, named Thomas, [and also] called "The Twin," was not with them when Jesus came.
