Leviticus 8:6-17

Then he presented Aaron and his sons and washed them with water. He put the official tunic on Aaron and tied the sash around his waist. He dressed him in the robe, placed the ephod on him, and attached the ephod securely with its decorative sash. Then Moses placed the chestpiece on Aaron and put the Urim and the Thummim inside it. He placed the turban on Aaron’s head and attached the gold medallion—the badge of holiness—to the front of the turban, just as the LORD had commanded him. Then Moses took the anointing oil and anointed the Tabernacle and everything in it, making them holy. He sprinkled the oil on the altar seven times, anointing it and all its utensils, as well as the washbasin and its stand, making them holy. Then he poured some of the anointing oil on Aaron’s head, anointing him and making him holy for his work. Next Moses presented Aaron’s sons. He clothed them in their tunics, tied their sashes around them, and put their special head coverings on them, just as the LORD had commanded him. Then Moses presented the bull for the sin offering. Aaron and his sons laid their hands on the bull’s head, and Moses slaughtered it. Moses took some of the blood, and with his finger he put it on the four horns of the altar to purify it. He poured out the rest of the blood at the base of the altar. Through this process, he made the altar holy by purifying it. Then Moses took all the fat around the internal organs, the long lobe of the liver, and the two kidneys and the fat around them, and he burned it all on the altar. He took the rest of the bull, including its hide, meat, and dung, and burned it on a fire outside the camp, just as the LORD had commanded him.
