Deuteronomy 18:3-4

WEB(i) 3 This shall be the priests’ due from the people, from those who offer a sacrifice, whether it be ox or sheep, that they shall give to the priest: the shoulder, the two cheeks, and the inner parts. 4 You shall give him the first fruits of your grain, of your new wine, and of your oil, and the first of the fleece of your sheep.
