EZK 47:12

12 And by the nachal upon the bank thereof, on this side and on that side, shall grow kol etz ma'achal, whose aleh [(leaf)] shall not fade, neither shall the p'ri thereof fail; it shall yield fresh fruit every month, because the mayim for them flowed out of the Mikdash; and the p'ri thereof shall be for food, and the aleh [(leaf)] thereof for terufah [(healing)].
