1 Kings 11:42

And the time that Solomon reigned in Jerusalem, over all Israel, was forty years. The same says Eupolemus z, an Heathen writer, who makes him to live but fifty two years; which is the common tradition of the Jews, who suppose he was but twelve years of age when he began to reign; which is to be confuted from the age of his son Rehoboam, see 1 Kings 14:21. Josephus a, on the other hand, makes him to live to too great an age, who says that he reigned eighty years, and lived to ninety four.
