'Venom' in the Bible

For their vine is from the stock of Sodom, and from the fields of Gomorrah. Their grapes contain venom, their clusters of grapes are bitter.

Their wine is snakes' poison, the deadly venom of cobras.

his food is turned sour in his stomach; it becomes the venom of serpents within him.

Their venom is like that of a snake, like a deaf serpent that does not hear,

Their tongues wound like a serpent; a viper's venom is behind their lips. (Selah)
