Deuteronomy 18:8

“They shall have like portions to eat, etc.] Equal parts of the sacrifices with the priests that usually ministered there; hence we learn, says Jarchi, that they divided the skins and flesh of the sin offerings; perhaps even such as did not come by virtue of the feast, as the daily sacrifices, and the additions of the sabbath, and the vows, and the freewill offerings: beside that which cometh by the sale of his patrimony: for though the priests and Levites had no inheritance divided to them in the land, yet they might buy houses and fields, and leave them to their children, and this may be called their patrimony; now it was not reasonable that they should wholly live upon this, or spend what…”

“like portions: Lev 7:8, Lev 7:9, Lev 7:14; Neh 12:44, Neh 12:47; Luk 10:7; Co1 9:7-14; Ti1 5:17, Ti1 5:18 that which cometh of the sale of his patrimony: Heb. his sales by the fathers Deuteronomy 18:9”
