7. Now when this purification, which their leader made upon the mourning for his sister, as it has been now described, was over, he caused the army to remove and to march through the wilderness and through Arabia; and when he came to a place which the Arabians esteem their metropolis, which was formerly called Arce, but has now the name of Petra, at this place, which was encompassed with high mountains, Aaron went up one of them in the sight of the whole army, Moses having before told him that he was to die, for this place was over against them. He put off his pontifical garments, and delivered them to Eleazar his son, to whom the high priesthood belonged, because he was the elder brother; and died while the multitude looked upon him. He died in the same year wherein he lost his sister, having lived in all a hundred twenty and three years. He died on the first day of that lunar month which is called by the Athenians Hecatombaeon, by the Macedonians Lous, but by the Hebrews Abba.
