Leviticus 2:2-3

²And he shall bring it to Aaron's sons the priests: and he shall take out of it his handful of its flour, and of its oil, with all its frankincense; and the priest shall burn the memorial of it upon the altar, to be an offering made by fire, of a sweet savor to the LORD:

³And the remnant 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.
