Harod Antpas and took the throne in 4BC, was Harod the Great's nephew. But most of the details in the biblical account are things associated with Herod the Great, not Harod Antipas There was some debate over which of them was the king mentioned in the story. The writers attributes things that both did. Harod the great, for example, had a stepdaughter, one of the central point in the story of John the Babtist, Harod Antipas did not have a stepdaughter. Most of the details of the biblical account point to Harod the great being King Harod.
Scholars debate whether Jesus was born earlier than they originally thought, during the reign of Harod the Great, who died in 4BC, or if the writers simply mixed up the two kings.
