'Bed' in the Bible

Someone told Jacob, and said, "Behold, your son Joseph comes to you," and Israel strengthened himself, and sat on the bed.

Boiling over as water, you shall not excel; because you went up to your father's bed, then defiled it. He went up to my couch.

When Jacob made an end of charging his sons, he gathered up his feet into the bed, and yielded up the spirit, and was gathered to his people.
