Food and venom metaphors

12Though evil is sweet in his mouth, he hides it under his tongue,

13He spares it and does not let it go, and holds it in his mouth.

14His food turns in his belly; it is the venom of poisonous snakes within him.

15He swallowed wealth, but he will vomit it up; God will drive it out of his belly.

16He sucks the venom of poisonous snakes; the tongue of a venomous snake kills him.

17He will not see the streams, the rivers, the brooks flowing with honey and curds.
