Wisdom of Solomon 7:22

20 the natures of animals and the tempers of wild animals, the powers of spirits and the thoughts of human beings, the varieties of plants and the virtues of roots; 21 I learned both what is secret and what is manifest, 22 for wisdom, the fashioner of all things, taught me. There is in her a spirit that is intelligent, holy, unique, manifold, subtle, mobile, clear, unpolluted, distinct, invulnerable, loving the good, keen, irresistible, 23 beneficent, humane, steadfast, sure, free from anxiety, all-powerful, overseeing all, and penetrating through all spirits that are intelligent, pure, and altogether subtle. 24 For wisdom is more mobile than any motion; because of her pureness she pervades and penetrates all things.

Ambrose On the Holy Spirit 3.6

But whither is the madness of faithless men leading us, so that we appear to be proving, as if it were a matter of doubt, that the Holy Spirit rebukes, whereas judges themselves are unable to judge, except through the Spirit. Lastly, that famous judgment of Solomon, when, among the difficulties arising from those who were contending, as one, having overlain the child which she had borne, wished to claim the child of another, and the other was protecting her own son, he both discovered deceit in the very hidden thoughts, and affection in the mother's heart, was certainly so admirable only by the gift of the Holy Spirit. For no other sword would have penetrated the hidden feeling of those women, except the sword of the Spirit, of which the Lord says: I am not come to send peace but a sword. For the inmost mind cannot be penetrated by steel, but by the Spirit: For the Spirit of understanding is holy, one only, manifold, subtle, lively, and, farther on, overseeing all things.
