5804. And a child of his old age, the youngest. That this signifies truth therefrom which is new, is evident from the representation of Benjamin, who is here the "child, the youngest," as being truth (of which above, n. 5801; as also that a "child" or "son" is truth, n. 489, 491, 1147, 2623, 3373); and from the signification of "old age," as being newness of life (see n. 3492, 4220, 4676). Hence it is plain that by a "child of old ages, the youngest," is signified truth which is new. The case herein is this. The man who is being regenerated and becoming spiritual is first led to good by means of truth; for man does not know what spiritual good, or what is the same thing, Christian good is, except through truth or through doctrine drawn from the Word. In this way he is initiated into good. Afterward, when he has been initiated, he no longer is led to good through truth, but to truth through good, for he then not only sees from good the truths which he knew before, but also from good brings forth new truths which he did not and could not know before; for good is attended with a longing for truths, because with these it is, as it were, nourished, it being perfected by them. These new truths differ greatly from the truths which he had previously known; for those which he then knew had but little life, while those which he now acquires have life from good.
[2] When a man has come to good by means of truth, he is "Israel;" and the truth which he then receives from good, that is, through good from the Lord, is new truth, which is represented by Benjamin while he was with his father. By means of this truth good becomes fruitful in the natural, and brings forth numberless truths wherein is good. In this way the natural is regenerated, and through fruitfulness first becomes like a tree with good fruits, and successively like a garden. From all this it is evident what is meant by new truth from spiritual good.
