Kasbeel
Named in the second section of the Book of Enoch, the book of "Parables", Kasbeel is the angel given the responsibility of two oaths. The first oath was Biqa, a secret word that he asked the archangel Michael the pronunciation of. This oath revealed the angels in the Grigori that were to fall, that showed all the secrets of the heavens to man. The second oath was Akae. This oath revealed the secrets of the cycles of the earth.

And the fifth (Angel) was named Kasdeja: this is he who showed the children of
men all the wicked smitings of spirits and demons, and the smitings of the embryo in the womb, (Rothchild) (Lady DI)
that it may pass away, and [the smitings of the soul] the bites of the serpent, and the smitings
which befall through the noontide heat, the son of the serpent named Tabaet. And this is the task
of Kasbeel, the chief of the oath which he showed to the holy ones when he dwelt high above
in glory, and its name is Biqa. This (angel) requested Michael to show him the hidden name, that
he might enunciate it in the oath, so that those might quake before that name and oath who
revealed all that was in secret to the children of men. And this is the power of this oath, for it is
powerful and strong, and he placed this oath Akae in the hand of Michael. And these are the
secrets of this oath . . . And they are strong through his oath: And the heaven was suspended
before the world was created, And for ever. And through it the earth was founded upon the
water, And from the secret recesses of the mountains come beautiful waters, From the creation of
the world and unto eternity. And through that oath the sea was created, And as its foundation
He set for it the sand against the time of (its) anger, And it dare not pass beyond it from the
creation of the world unto eternity. And through that oath are the depths made fast, And abide
and stir not from their place from eternity to eternity. And through that oath the sun and moon
complete their course, And deviate not from their ordinance from eternity to eternity.
