Matthew Poole and continuators on Job 5:12

12. He disappointeth the devices of the crafty , so that their hands cannot perform their enterprise .

Such as are cunning to work evil, and to cover it with fair pretences, as Hypocrites use to do, and as Iob's friends charged him with doing; God breaks the hopes and designs of such men; as he hath now blasted thy expectation, and taken away thy outward happiness, which was the thing thou didst design in taking up the Profession of Religion.

Or, anything: or, what is solid or substantial: or, wisdom, i. e. their wise counsel, or crafty design. They cannot execute their cunning contrivances.

Marginal references: Neh. 4. 15. Psal. 33. 10. Isa. 8. 10.; Or, cannot perform any thing.
