1CH 6:49

49 Aaron and his descendants were the ones who placed on the altar the sacrifices that were to be burned completely, and they burned incense on another altar. Those sacrifices were in order that Yahweh would no longer be angry with the people of Israel for having sinned. Those men also did other work in the Very Holy Place in the sacred tent, obeying the instructions that Moses, who served God [well], had given to them.
