Leviticus 2:10
And that which is left of the meat offering shall be Aaron’s and his sons’: it is a thing most holy of the offerings of the LORD made by fire. And that which is left of the meat offering shall be Aaron’s and his sons’: it is a thing most holy of the offerings of the LORD made by fire.
The term rendered meat signifies food in general rather than animal flesh. The second chapter of Leviticus establishes that the Jewish meat offerings were prepared from flour and oil. The portion of that flour-and-oil offering that remained was assigned to Aaron and his sons.
