'Bed' in the Bible

And behold, men bring on a bed a man that was palsied: and they sought to bring him in, and to lay him before him.

And no man, when he hath lighted a lamp, covereth it with a vessel, or putteth it under a bed; but putteth it on a stand, that they that enter in may see the light.

and he from within shall answer and say, Trouble me not: the door is now shut, and my children are with me in bed; I cannot rise and give thee?

I say unto you, In that night there shall be two men on one bed; the one shall be taken, and the other shall be left.
