'Viper' in the Bible

Don’t rejoice, all of you in Philistia,because the rod of the one who struck you is broken.For a viper will come from the root of a snake,and from its egg comes a flying serpent.

The burden of the beasts of the south: into the land of trouble and anguish, from whence come the young and old lion, the viper and fiery flying serpent, they will carry their riches upon the shoulders of young asses, and their treasures upon the bunches of camels, to a people that shall not profit them.

They hatch cockatrice' eggs, and weave the spider's web: he that eateth of their eggs dieth, and that which is crushed breaketh out into a viper.
