'Exterminated' in the Bible

And Zedekiah the son of Chenaanah made for himself horns of iron, and he said, Thus saith Jehovah: With these shalt thou push the Syrians, until thou have exterminated them.

And when Athaliah the mother of Ahaziah saw that her son was dead, she rose up and exterminated all the royal seed of the house of Judah.
