Numbers 18:18-19

18However, their 1meat shall be yours; it shall be yours like the 2breast of a wave offering and like the right thigh.

193All the offerings of the holy gifts, which the sons of Israel offer to the Lord, I have given to you and your sons and your daughters with you, as a permanent allotment. It is 4a permanent covenant of salt before the Lord to you and your 5descendants with you.”
