57. The “herb bearing seed” is every truth which regards use; the “tree in which is fruit” is the good of faith; “fruit” is what the Lord gives to the celestial man, but “seed producing fruit” is what He gives to the spiritual man; and therefore it is said, the “tree yielding seed, to you it shall be for food.” That celestial food is called fruit from a tree, is evident from the following chapter, where the celestial man is treated of. In confirmation of this we will here cite only these words of the Lord from Ezekiel:

By the river, upon the bank thereof, on this side and on that side, there cometh up every tree of food, whose leaf shall not fade, neither shall the fruit thereof be consumed; it is born again in its month; because these its waters issue out of the sanctuary; and the fruit thereof shall be for food, and the leaf thereof for medicine (Ezekiel 47:12).

“Waters issuing out of the sanctuary” signify the life and mercy of the Lord, who is the “sanctuary.” “Fruit” is wisdom, which shall be food for them; the “leaf” is intelligence which shall be for their use, and this use is called “medicine.” But that spiritual food is called “herb” appears from David: My shepherd, I shall not want; Thou makest me to lie down in pastures of herb (Psalms 23:1-2).
