1 Chronicles 29:26-30

David son of Jesse ruled over all Israel. He was king for forty years. He ruled from Hebron seven years and from Jerusalem thirty-three. He died at a ripe old age, full of days, wealth, and glory. His son Solomon ruled after him. The history of David the king, from start to finish, is written in the chronicles of Samuel the seer, Nathan the prophet, and Gad the seer, including a full account of his rule, his exploits, and the times through which he and Israel and the surrounding kingdoms passed.
