'Twelve' in the Bible

So they gathered them up, and filled twelve baskets with broken pieces from the five barley loaves, which were left over by those who had eaten.

Jesus said therefore to the twelve, "You don't also want to go away, do you?"

Jesus answered them, "Didn't I choose you, the twelve, and one of you is a devil?"

Now he spoke of Judas, the son of Simon Iscariot, for it was he who would betray him, being one of the twelve.

Jesus answered, "Aren't there twelve hours of daylight? If a man walks in the day, he doesn't stumble, because he sees the light of this world.

But Thomas, one of the twelve, called Didymus, wasn't with them when Jesus came.
