Numbers 18:8-9

Then the  Lord spoke to Aaron, “Behold, a 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 b as a portion and to your sons as a perpetual due. This shall be yours of the most holy things, reserved from the fire: every offering of theirs, every grain offering of theirs and every c sin offering of theirs and every d guilt offering of theirs, which they render to me, shall be most holy to you and to your sons.
