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.

5804. 'And a child of his old age, the youngest one' means truth that is new, springing from that good. This is clear from the representation of Benjamin, to whom 'a child, the youngest one' refers here, as truth, dealt with above in 5801, in addition to which 'child' or 'son' means truth, see 489, 491, 1147, 1623, 3373; and from the meaning of 'old age' as newness of life, dealt with in 3492, 4620, 4676. From this it is evident that 'a child of his old age, the youngest one' means truth that is new. The implications of this are as follows: A person who is being regenerated and becoming spiritual is led initially by means of truth to good; for a person does not know what spiritual good is, or what amounts to the same, what Christian good is, except through truth, that is, through teaching drawn from the Word. This is the way he is introduced into good. After that, once he has been introduced into it, he is led no longer by means of truth to good, but by means of good to truth; for at this point good not only enables him to see the truths he knew previously but also brings forth new ones he did not and could not know previously. Good holds the desire for truths within itself because it is so to speak nourished by them; indeed they make it more perfect. These truths - the new ones - are very different from the truths he knew before; for the truths he knew before possessed little life in them. But those which he receives afterwards possess life coming from good.

[2] Once a person has by means of truth arrived at good he is 'Israel', and the truth which he now receives from good, that is, from the Lord through good, is the new truth that 'Benjamin' represented all the time he was with his father. By means of this truth good in the natural bears fruit, bringing forth countless truths that hold good within them. This is the way the regeneration of the natural proceeds, becoming by its fruitfulness first of all like a tree with good fruit on it and then gradually like a garden. All this shows what is meant by new truth springing from spiritual good.
