And one told Jacob, and said, Behold, thy son Joseph cometh unto thee: and Israel strengthened himself, and sat upon the bed.

Boiling over as water, thou shalt not have the pre-eminence; Because thou wentest up to thy father's bed; Then defiledst thou it: he went up to my couch.

And when Jacob made an end of charging his sons, he gathered up his feet into the bed, and yielded up the ghost, and was gathered unto his people.
