Jamieson, Fausset & Brown, on Ezek 47:12

“And by the torrent on the banks thereof on both sides shall grow all trees that bear fruit: their leaf shall not fall off, and their fruit shall not fail: every month shall they bring forth firstfruits, because the waters thereof shall issue out of the sanctuary: and the fruits thereof shall be for food, and the leaves thereof for medicine.”

“Instead of the "vine of Sodom and grapes of Gomorrah" (Deu 32:32), nauseous and unwholesome, trees of life-giving and life-restoring virtue shall bloom similar in properties to, and exceeding in number, the tree of life in Eden (Rev 2:7; Rev 22:2, Rev 22:14). leaf . . . not fade--expressing not only the unfailing character of the heavenly medicine of the tree of life, but also that the graces of the believer (as a tree of righteousness), which are the leaves, and his deeds, which are the fruits that flow from those graces, are immortal (Psa 1:3; Jer 17:8; Mat 10:42; Co1 15:58). new fruit--literally, "firstlings," or first fruit. They are still, each month afresh, as it were, yielding their first-fruit [FAIRBAIRN]. The first-born of a thing, in Hebrew idiom, means the chiefest. As Job 18:13, "the first-born of death," that is, the most fatal death.”
