'Bed' in the Bible

Then he said, "Swear to me." And he swore to him. Then Israel bowed himself on the head of the bed.

And it was told to Jacob, "Behold, your son Joseph has come to you." Then Israel strengthened himself and he sat up in the bed.

Unstable as water, you shall not excel [any longer], for you went up upon the bed of your father, then defiled [it]. You went up upon my couch!

When Jacob finished instructing his sons he drew his feet up to the bed. Then he took his last breath and was gathered to his people.
