'Bed' in the Bible

He said, “Swear to me.” So he swore to him. Then Israel bowed in worship at the head of the bed.

When it was told to Jacob, “Behold, your son Joseph has come to you,” Israel collected his strength and sat up in the bed.

“Uncontrolled as water, you shall not have preeminence,Because you went up to your father’s bed;Then you defiled it—he went up to my couch.

When Jacob finished charging his sons, he drew his feet into the bed and breathed his last, and was gathered to his people.
