1 Kings 11:42

And the time that Solomon reigned in Jerusalem, over all
Israel, was forty years.
] The same says Eupolemus ^F26, 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 ^F1, 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.
