1 Kings Chapter 2:
10 Then David slept with his fathers, and was buried in the city of David. 11 And the time that David reigned over Israel was forty years; he reigned seven years in Hebron, and thirty-three years in Jerusalem. 12 So Solomon sat upon the throne of David his father; and his kingdom was firmly established.
