Abishua is mentioned in the books 1 Chronicles (6:35) and Ezra (7:5) as the son of the High Priest Phinehas, son of Eleazar. As such, he is the great-grandson of Aaron, the brother of Moses and first High Priest. It is likely that Abishua was a contemporary of the Israelite judge Ehud and the Moabite king Eglon.[1]
