'Twelve' in the Bible

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

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

Jesus replied, "Didn't I choose you, the twelve, and yet one of you is the devil?"

(Now he said this about Judas son of Simon Iscariot, for Judas, one of the twelve, was going to betray him.)

Jesus replied, "Are there not twelve hours in a day? If anyone walks around in the daytime, he does not stumble, because he sees the light of this world.

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