Job 20:12-16

12Though evil is sweet in his mouth and he conceals it under his tongue,13though he cannot bear to let it go and keeps it in his mouth,14yet in his stomach his food sours into the venom of cobras within him.15He swallows wealth but vomits it out; God will force it from his stomach.16He will suck the poison of cobras; the fangs of a viper will kill him.
