'Bed' in the Bible

Michal took the teraphim, and laid it in the bed, and put a pillow of goats' [hair] at its head, and covered it with the clothes.

Saul sent the messengers to see David, saying, "Bring him up to me in the bed, that I may kill him."

When the messengers came in, behold, the teraphim was in the bed, with the pillow of goats' hair at its head.

But he refused, and said, I will not eat. But his servants, together with the woman, constrained him; and he listened to their voice. So he arose from the earth, and sat on the bed.
