'Bed' in the Bible

‘Your pomp and the music of your harpsHave been brought down to Sheol;Maggots are spread out as your bed beneath youAnd worms are your covering.’

For the bed is shorter than that a man can stretch himself on it: and the covering narrower than that he can wrap himself in it.

See, all you who make a fire, arming yourselves with burning branches: go in the flame of your fire, and among the branches you have put a light to. This will you have from my hand, you will make your bed in sorrow.

Wasn’t it You who dried up the sea,the waters of the great deep,who made the sea-bed into a roadfor the redeemed to pass over?

Upon a lofty and high mountain hast thou set thy bed: even thither wentest thou up to offer sacrifice.

Behind the doors also and the posts hast thou set up thy remembrance: for thou hast discovered thyself to another than me, and art gone up; thou hast enlarged thy bed, and made thee a covenant with them; thou lovedst their bed where thou sawest it.

“Is it a fast like this which I choose, a day for a man to humble himself?Is it for bowing one’s head like a reedAnd for spreading out sackcloth and ashes as a bed?Will you call this a fast, even an acceptable day to the Lord?
