1"`When anyone offers an offering of a meal-offering to Yahweh, his offering shall be of fine flour; and he shall pour oil on it, and put frankincense on it. 2He shall bring it to Aaron`s sons the priests; and he shall take his handful of its fine flour, and of its oil, with all its frankincense; and the priest shall burn the memorial of it on the altar, an offering made by fire, of a sweet savor to Yahweh. 3That which is left of the meal-offering shall be Aaron`s and his sons`. It is a most holy thing of the offerings of Yahweh made by fire.
