Leviticus 6:8-13

8So he is to lift up from it his handful of the fine flour of the grain offering, with some of its oil and all the frankincense which is on the grain offering, and burn it up as smoke on the altar for a soothing aroma, as its memorial portion to Adonai.

9Then what is left from it Aaron and his sons are to eat. It is to be eaten as matzah in a holy place, in the courtyard of the Tent of Meeting.

10It must not be baked with hametz. I have given it as their portion of My offerings made by fire. It is most holy, like the sin offering and like the trespass offering.

11Every male among the children of Aaron may eat it, as their portion forever throughout your generations from the offerings of Adonai made by fire. Whoever touches them will become holy.”

12Adonai spoke to Moses, saying:

13“This is the offering of Aaron and his sons, which they are to offer to Adonai on the day when he is anointed: the tenth part of an ephah of fine flour for a continual grain offering, half of it in the morning, and half of it in the evening.
