Deuteronomy 18:2-4

New Century Version

² They will not inherit any of the land like their brothers, but they will inherit the Lord himself, as he has promised them.

³ When you offer a bull or sheep as a sacrifice, you must share with the priests, giving them the shoulder, the cheeks, and the inner organs. ⁴ Give them the first of your grain, new wine, and oil, as well as the first wool you cut from your sheep.
