1 Chronicles 6:48-50

New International Version

⁴⁸ Their fellow Levites^(A) were assigned to all the other duties of the tabernacle, the house of God. ⁴⁹ But Aaron and his descendants were the ones who presented offerings on the altar^(B) of burnt offering and on the altar of incense^(C) in connection with all that was done in the Most Holy Place, making atonement for Israel, in accordance with all that Moses the servant of God had commanded.
