1 Chronicles 29:26-30

26Now David the son of Jesse reigned over all Israel. 27And the time that he reigned over Israel was forty years: he reigned seven years in Hebron, and he reigned thirty-three years in Jerusalem. 28And he died in a good old age, full of days, riches, and honour; and Solomon his son reigned in his stead. 29And the acts of David the king, first and last, behold, they are written in the book of Samuel the seer, and in the book of Nathan the prophet, and in the book of Gad the seer; 30with all his reign and his might, and the times that passed over him, and over Israel, and over all the kingdoms of the countries.
