Drinketh up scorning like water? - This is a repetition of the charge made against Job by Eliphaz, Job 15:16. It is a proverbial expression, and seems to be formed, as a metaphor, from a camel drinking, who takes in a large draught of water, even the most turbid, on its setting out on a journey in a caravan, that it may serve it for a long time. Job deals largely in scorning; he fills his heart with it.
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.
