Does the word "Trinity" exist anywhere in the Bible?

The word "trinity" does not occur in the Bible.  The idea
of the trinity has a basis in the Bible, but the actual term itself does not appear in
the Bible.

The idea of the trinity does clearly show up in
the Bible.  For example, in Matthew Chapter 28 Verse 19, Jesus is telling his disciples
(this is after the Resurrection) to go and convert people.  He tells them that they
should go out and baptize people in the name of the Father and of the Son and of the
Holy Spirit.

So, in this verse, we clearly see an example
of where the concept of the trinity comes from.  The verse refers to all three parts of
the trinity and puts them in a context that implies that they are all equal parts of the
Godhead.  However, the word "trinity" does not appear.
