Albert Barnes Commentary Job 34:7

"What man is like Job, Who drinketh up scoffing like water," — Job 34:7 (ASV)

What man is like Job, who drinketh up scorning like water? - A similar image occurs in (Job 15:16). The idea is, that he was full of reproachful speeches respecting God; of the language of irreverence and rebellion. He indulged in it as freely as a man drinks water; gathers up and imbibes all the language of reproach that he can find, and indulges in it as if it were perfectly harmless.
