She is a tree of life to them that lay hold upon her: and happy is everyone that retains her.
All Commentaries on Proverbs 3:18 Go To Proverbs 3
Hilary of Poitiers
AD 368
In the book of Genesis, where the lawgiver depicts the paradise planted by God, we are shown that every tree is fair to look upon and good for food. It is also stated that there stands in the midst of the garden a tree of life and a tree of the knowledge of good and evil. Next, [we are told] that the garden is watered by a stream that divides into four heads. The prophet Solomon teaches us what this tree of life is in his exhortation concerning wisdom: “She is a tree of life to all them that lay hold upon her and lean upon her.” This tree then is living; and not only living, but, furthermore, guided by reason. Guided by reason, that is, in so far as to yield fruit, and not casually nor unseasonably, but in its own season. And this tree is planted beside the rills of water in the domain of the kingdom of God, that is, of course, in paradise and in the place where the stream as it issues forth is divided into four heads.
