Numbers 18:18-19

18The meat of these animals will be yours, just like the breast and right thigh that are presented by lifting them up as a special offering before the altar.

19Yes, I am giving you all these holy offerings that the people of Israel bring to the Lord. They are for you and your sons and daughters, to be eaten as your permanent share. This is an eternal and unbreakable covenant between the Lord and you, and it also applies to your descendants.”
