2 Peter 2:4-6

for since God did not spare the angels, who had sinned, but having precipitated them to hell, confin'd them to chains of darkness, where they are reserv'd for judgment:

Revelation 2:10

fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life.

Revelation 3:11

behold, I come quickly: hold that fast which you have, let no man take your crown.
