exarch

And I questioned him, and said: "Who art thou?" The demon replied: "I am Beelzebub, the exarch of the demons. And all the demons have their chief seats close to me. And I it is who make manifest the apparition of each demon." And he promised to bring to me in bonds all the unclean spirits. And I again glorified the God of heaven and earth, as I do always give thanks to him.
