Joseph died, and all his brothers, and all that generation (Exodus 1:6).
Genesis 50:26 states that Joseph was embalmed and placed in a coffin in Egypt. Perhaps his other family members were given similar treatment when they died, although it may also be that Joseph’s treatment was special, due to his elevated status in Egypt. This display of Egyptian mummies and coffins was photographed at the Michael C. Carlos Museum at Emory University.
