Leviticus 9:10-12

Amplified Bible

¹⁰ but the fat, the kidneys, and the lobe of the liver from the sin offering he offered up in smoke on the altar, just as the Lord had commanded Moses. ¹¹ And Aaron burned the meat and the hide in the fire outside the camp.

¹² Then he killed the burnt offering; and Aaron’s sons handed the blood to him and he sprinkled it around on the altar.
