My cup runneth over

Epidemiologists counter that such small studies don't mirror real-world conditions, and they can't examine the long-term risk of disease.

My cup runneth over

Meaning

I have more than enough for my needs.

Origin

From the Bible, Psalms 23:5 (King James Version):

Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.
