The sons of Aaron make offerings (1 Chr 6:49-6:53)

“Aaron and his sons made offerings upon the altar of burnt offering and upon the altar of incense for all the work of the most holy place. They were making atonement for Israel, according to all that Moses the servant of God had commanded. These are the sons of Aaron, Eleazar his son, Phinehas his son, Abishua his son, Bukki his son, Uzzi his son, Zerahiah his son, Meraioth his son, Amariah his son, Ahitub his son, Zadok his son, and Ahimaaz his son.”

This list of Aaron and his sons is exactly the same as the list of the high priests before the building of the Temple at Jerusalem in the early part of this chapter. These priest sons of Aaron could make sacrifices on the altar, in particular the burnt offerings. They did atonement for the people of Israel according to the Law of Moses.  However, after the listing of Eleazar, Phinehas, Abishua, Bukki, Uzzi, Zerahiah, Meraioth, Amariah, Ahitub, Zadok, and Ahimaaz, the list stops. There is no mention of any of the high priests after the building of the Temple in Jerusalem by Solomon as earlier in this chapter.
