Leviticus 6:15-16

15And he shall take of it his handful of the fine flour of the oblation, and of the oil thereof, and all the frankincense which is on the meat-offering, and shall burn [it] on the altar: [it is] a sweet odour of the memorial thereof to Jehovah.

16And the remainder thereof shall Aaron and his sons eat: unleavened shall it be eaten in a holy place; in the court of the tent of meeting shall they eat it.
