Numbers 18:8-21

8Then the LORD spoke to Aaron, “Behold, I have given you charge of the contributions made to me, all the consecrated things of the people of Israel. I have given them to you as a portion and to your sons as a perpetual due. 9This shall be yours of the most holy things, reserved from the fire: every offering of theirs, every grain offering of theirs and every sin offering of theirs and every guilt offering of theirs, which they render to me, shall be most holy to you and to your sons. 10In a most holy place shall you eat it. Every male may eat it; it is holy to you. 11This also is yours: the contribution of their gift, all the wave offerings of the people of Israel. I have given them to you, and to your sons and daughters with you, as a perpetual due.

It is a covenant of salt forever before the LORD for you and for your offspring with you.” 20And the LORD said to Aaron, “You shall have no inheritance in their land, neither shall you have any portion among them.
