And David Slept with His Fathers

In recording King David's death, the Bible states, "And David slept with his fathers" (I Kings 2:10). Why does it not state, "And David died"?

The  Sages  answered their  own  question: "David was survived by a son  who  followed the good  ways  of his  father's life,  continuing his  father's noble  deeds. Therefore, it  could  not  be  said  that  David  was  really dead, for  he  lived  on  through the  good  deeds of his son."
