2 Peter 2:4
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:
and the angels which kept not their original dignity, but deserted their proper abode, he hath reserved in everlasting chains under darkness, to the judgment of the great day.

besides, how could any one enter into the house of a man of might to rob him of his goods, except he first master the strong man? and then indeed he might plunder his house.
no one can enter into a strong man's house, and plunder his goods, unless the man be first secur'd.
but if a stronger than he should assault, and overcome him, he will strip him of all his furniture on which he relyed, and divide the plunder.
