'Viper' in the Bible

The burden of the beasts of the South. Through the land of trouble and anguish, from whence come the lioness and the lion, the viper and fiery flying serpent, they carry their riches upon the shoulders of young asses, and their treasures upon the humps of camels, to a people that shall not profit them .

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