Job 20:14 in the King James Version
Yet his meat in his bowels is turned, it is the gall of asps within him.
Context
13 though he spare it, and will not let it go, but keep it still within his mouth,
14 yet his food in his bowels is turned. It is cobra venom within him.
15 He has swallowed down riches, and he will vomit them up again. God will cast them out of his belly.
