Ezekiel 44:28-30

“The priests will not have any property or possession of land, for I alone am their special possession. Their food will come from the gifts and sacrifices brought to the Temple by the people—the grain offerings, the sin offerings, and the guilt offerings. Whatever anyone sets apart for the LORD will belong to the priests. The first of the ripe fruits and all the gifts brought to the LORD will go to the priests. The first batch of dough must also be given to the priests so the LORD will bless your homes.
