Michael, Liber Mysteriorum Secundus 21 March 1582 quoted from Part VII: The “Seven” Thrones in In Operibus Sigillo Dei Aemeth by David Richard Jones.

“O God, O God, O God,
Thy Name (O God,) be praised ever,
from thy 7 Thrones
from thy 7 Trumpets
and thy 7 Angels
in 7, God wrought all things” [via]
