'Kept' in the Bible

For if God didn’t spare the angels who sinned but threw them down into Tartarus and delivered them to be kept in chains of darkness until judgment;

And did not have mercy on the world which then was, but only kept safe Noah, a preacher of righteousness, with seven others, when he let loose the waters over the world of the evil-doers;

And kept safe Lot, the upright man, who was deeply troubled by the unclean life of the evil-doers

These are wells without water, and clouds by a tempest driven, to whom the thick gloom of the darkness to the age hath been kept;

But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
