Job 20:14

12“Though wickedness is sweet in his mouth, though he hide it under his tongue,

13though he spare it, and will not let it go, but keep it still within his mouth,

14yet his food in his bowels is turned. It is cobra venom within him.

15He has swallowed down riches, and he will vomit them up again. God will cast them out of his belly.

16He will suck cobra venom. The viper’s tongue will kill him.
