One of the fallen angels mentioned in the Book of Enoch, "the chief of the oath, who showed the oath to the Holy ones when he dwelt on high in glory. And his name is Beqa. And this one told the Holy Michael that he should show him the secret name so that they might mention it in the oath, so that those, who showed the sons of men everything that is secret, trembled before that name and oath. And this is the power of this oath, for it is powerful and strong, and he placed this oath, Akae, in the charge of the Holy Michael. And these are the secrets of this oath, and they are strong through this oath, and Heaven was suspended, before the world was created, and forever."
