End of the 40 Year Reign of King Solomon and his death
41 As for the other events of Solomon's reign—all he did
and the wisdom he displayed—are they not written in the book of the
annals of Solomon? 42 Solomon reigned in Jerusalem over all
Israel forty years. 43 Then he rested with his fathers and
was buried in the city of David his father. And Rehoboam his son succeeded him as king.
