In 1.22.1 of Josephus’ Antiquities, he states that Isaac died at 185 years. The Masoretic text clearly states that he died at 180. “Now the days of Isaac were one hundred and eighty years. Isaac breathed his last and died and was gathered to his people, an old man of ripe age; and his sons Esau and Jacob buried him.” Genesis 35:28-29

Why he stated the age so clearly wrong?  It’s hard to tell, but Josephus’ chronology in other places is also wrong.
