Ben Sira 45:20

20 Then he rewarded Aaron again, giving him a special honor: the right to the offerings of the first produce, so that the priests should have enough to eat.

Ben Sira 45:20 In-Context

18 Once, while the people were in the wilderness, an angry group of jealous outsiders conspired against Moses. These were Dathan, Abiram, and Korah with their supporters.
19 The Lord saw what they were doing and became angry, so furious that he performed a miracle and destroyed them in a blazing fire.
20 Then he rewarded Aaron again, giving him a special honor: the right to the offerings of the first produce, so that the priests should have enough to eat.
21 Their food is the sacrifices offered to the Lord; the Lord gave this to Aaron and his descendants.
22 But Aaron, unlike the rest of the people, was to inherit no land, no special portion of his own. The Lord himself would be all he needed.
