In chapter 7 of the book of Wisdom the path to Wisdom and her defining virtues were given:
7 Therefore I prayed, and understanding was given me;
I called on God, and the spirit of wisdom came to me.
8 I preferred her to scepters and thrones,
and I accounted wealth as nothing in comparison with her.
9 Neither did I liken to her any priceless gem,
because all gold is but a little sand in her sight,
and silver will be accounted as clay before her.
10 I loved her more than health and beauty,
and I chose to have her rather than light,
because her radiance never ceases.
11 All good things came to me along with her,
and in her hands uncounted wealth.
12 I rejoiced in them all, because wisdom leads them;
but I did not know that she was their mother.
13 I learned without guile and I impart without grudging;
I do not hide her wealth,
14 for it is an unfailing treasure for mortals;
those who get it obtain friendship with God,
commended for the gifts that come from instruction.
[...]
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.
