'Viper' in the Bible

Dan shall be a serpent on the way, a viper on the road that bites the heels of a horse, so that its rider falls backward.

Their venom [is] like snake venom; [They are] like a deaf viper that closes its ear

You will tread on lion and viper; you will trample young lion and serpent.

They sharpen their tongue as [sharp as] a snake's; [the] venom of a viper [is] under their lips. Selah

You must not rejoice, all you Philistines, that the rod that struck you is broken, for a viper will come forth from [the] root of [the] snake, and its fruit [will be] a flying serpent.

they hatch viper eggs, and they weave a spider web. One who eats their eggs dies, and that which is pressed is hatched [as] a serpent.
