'Kept' in the Bible

For if God did not have pity for the angels who did evil, but sent them down into hell, to be kept in chains of eternal night till they were judged;

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 fountains without water, and mists before a driving storm; for whom the eternal night is kept in store.

But the present heaven and the present earth have been kept for destruction by fire, which is waiting for them on the day of the judging and destruction of evil men.
