Unearth, expose (5,2,5)
I believe the answer is:
bring to light
I believe this is a double definition.
'unearth' is the first definition.
(I've seen this before)
'expose' is the second definition.
(I've seen this before)
(Other definitions for bring to light that I've seen before include "what one might do with spill" , "Unearth" , "Expose" , "Reveal" .)
