9:1 A star fall: This may mean the fall and apostasy of great and learned men from the true faith. Or a whole nation falling into error and separating from the church, not having the sign of God in their foreheads. And there was given to him the key of the bottomless pit. . .That is, to the angel, not to the fallen star. To this angel was given the power, which is here signified by a key, of opening hell.
