Destroy the children of fornication and the children of the Watchers from amongst men

through the works that were taught by Azazel: to him ascribe all sin.’ And to Gabriel said the Lord: ‘Proceed against the bastards and the reprobates, and against the children of fornication: and destroy [the children of fornication and] the children of the Watchers from amongst men [and cause them to go forth]: send them one against the other that they may destroy each other in battle (1 Enoch 10:9)
