Leviticus 6:14-17

¹⁴And this is the law of the oblation: one of the sons of Aaron shall present it before Jehovah, before the altar.

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.

¹⁷It shall not be baken with leaven. As their portion have I given it unto them of my offerings by fire: it is most holy; as the sin-offering, and as the trespass-offering.
