'Twelve' in the Bible

So they gathered them up, 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 answered them, “Did I Myself not choose you, the twelve, and yet one of you is a devil?”

Now He meant Judas the son of Simon Iscariot, for he, one of the twelve, was going to betray Him.

Jesus answered, “Are there not twelve hours in the day? If anyone walks in the day, he does not stumble, because he sees the light of this world.

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