1 Chronicles 29:26-30

²⁶Thus David the son of Jesse reigned over all Israel. ²⁷The time that he reigned over Israel was forty years; he reigned seven years in Hebron, and thirty-three years in Jerusalem. ²⁸Then he died in a good old age, full of days, riches, and honor; and Solomon his son reigned in his stead. ²⁹Now the acts of King David, from first to last, are written in the Chronicles of Samuel the seer, and in the Chronicles of Nathan the prophet, and in the Chronicles of Gad the seer, ³⁰with accounts of all his rule and his might and of the circumstances that came upon him and upon Israel, and upon all the kingdoms of the countries.
