57. 'The plant yielding seed' is every truth that looks towards a use. 'The tree in which there is fruit' is the good that accompanies faith. 'Fruit' is what the Lord gives to the celestial man, while 'seed', the source of the fruit, is what He gives to the spiritual man. This is why it is said that 'the tree producing seed will be for you for food'. That celestial food is called 'fruit from a tree' is clear from the next chapter where the subject is the celestial man. Here let just that be mentioned which the Lord spoke through Ezekiel,

Beside the river there is rising up upon its bank, on this side and on that, every tree for food. Its leaf will not fall nor its fruit fail. It is re-born monthly, for its waters flow out from the Sanctuary, and its fruit will be for food, and its leaf for medicine. Ezekiel 47:12.

'Waters from the Sanctuary' means the life and mercy of the Lord, who is the Sanctuary; 'fruit' means wisdom, which is food for them; 'leaf' is intelligence, which is given them for a use, which is called 'medicine'. Spiritual food however is called 'a plant', as stated through David,

[Jehovah is] my Shepherd, I shall not want; He makes me ¹ lie down in green pastures. ² Psalms 23:1-2.

Footnotes:

7133. 'Saying, Finish your work, your stint for the day' means that they should serve falsities so called in every state. This is clear from the meaning of 'finishing your work' as serving falsities (for fabrications and falsities which are introduced are meant by 'making bricks', see 7113, and since these are the work which they were to finish, an insistence that they should serve them is meant; the expression 'falsities so called' is used because falsities are considered by the evil who utter them to be not falsities but truths); and from the meaning of 'stint for the day' as in every state - 'day' meaning state, see 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850.
