'Bed' in the Bible

Now King David was old, advanced in years; they covered him with clothes, but he could not get warm.

And moreover the king's servants came to bless our lord king David, saying, God make the name of Solomon better than thy name, and make his throne greater than thy throne. And the king bowed himself upon the bed.

And he said unto her, Give me thy son. And he took him out of her bosom, and carried him up into a loft, where he abode, and laid him upon his own bed.

And Ahab came into his house heavy and displeased because of the word which Naboth the Jezreelite had spoken to him: for he had said, I will not give thee the inheritance of my fathers. And he laid him down upon his bed, and turned away his face, and would eat no bread.
