'Viper' in the Bible

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.
