How Full is Full?

I was reading Luke 6:45 this morning and was wondering about the word "perisseumatos," so i did a word study on "perisseuma" using the tools at www.zhubert.com.

As you can see, Qoheleth did not display in the NASB from the database so I looked in my LXX which translated it, "And I said in my heart, As the event of the fool is, so shall it be to me, even to me; and to what purpose have I gained wisdom? I said moreover in my heart, This is also vanity, because the fool speaks of his abundance."

So my question is, "Are we speaking of that which spills over, an overabundance, or simply full?"

Note the Mark 8 passage where they took up what was left over.
As we fill ourselves up with God's Word, what will spill out?
