1 Chronicles 24:19

These were the orderings of them in their service; in this order and method they were to come to perform the offices of the temple. To come into the house of the Lord, according to their manner, i.e. to come into the temple every sabbath day, and to continue there all the week long until the next sabbath, when they were relieved by others, as the manner was: see 2 Kings 11:5 1 Chronicles 9:25. Under Aaron their father, i.e. under the inspection and direction of the high priest, whom he calls Aaron, because he represented his person, and executed his office, and also came out of his loins, and their father, because of the authority which by God's appointment he had over them, and that love, reverence, and obedience which they owed to him.
