'Twelve' in the Bible

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

So Jesus said to the twelve, "You do not want to go away also, [do you]?"

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

(Now he was speaking about Judas [son] of Simon Iscariot, because this one--one of the twelve--was going to betray him.)

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

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