'Bed' in the Bible

and from inside he answers, ‘Do not bother me; the door has already been shut and my children and I are in bed; I cannot get up and give you anything.’

I tell you, on that night [when Messiah comes again] there will be two [sleeping] in one bed; the one (the non-believer) will be taken [away in judgment] and the other (the believer) will be left.
