Herod the Great (1959)

Herod, King of Judea, is made a prisoner by the Romans. Convinced the King is dead, his faithful lieutenant, Aaron, is nevertheless unable to keep his promise to kill the Queen if something untoward happened to the King. He leads the young woman out into the desert. Herod's pleas to Augustus are successful and he returns to his palace. His son, Antipater, informs Herod that Aaron has betrayed him.
