Numbers 18:11-13

¹¹And this shall be to you of the first-fruits of their gifts, of all the wave-offerings of the children of Israel; to thee have I given them and to thy sons and thy daughters with thee, a perpetual ordinance; every clean person in thy house shall eat them.

¹²Every first-offering of oil, and every first-offering of wine, their first-fruits of corn, whatsoever they may give to the Lord, to thee have I given them.

¹³All the first-fruits that are in their land, whatsoever they shall offer to the Lord, shall be thine: every clean person in thy house shall eat them.
