'Bed' in the Bible

"No one, when he has lit a lamp, covers it with a container, or puts it under a bed; but puts it on a stand, that those who enter in may see the light.

and he from within will answer and say, 'Don't bother me. The door is now shut, and my children are with me in bed. I can't get up and give it to you'?

I tell you, in that night there will be two people in one bed. The one will be taken, and the other will be left.
