Now before we take our stand at the window and look through the lattice into the street, we must notice the exhortations to the young man to make wisdom and understanding his intimate friends, with which the chapter begins. The law is to be kept as the apple of the eye, which is so sensitive, so tender, and at the same time so surpassingly important, that the lid has to shield it by a quick instinctive movement outrunning thought, and the hand has to be ready at all times to come to its succour. The commandments are to be written on the fingers, like engraved rings, which would serve as instant reminders in unwary moments; the very instruments through which the evil would be done are to be claimed and sealed and inscribed by the righteousness which can preserve from evil, while in the secret tablets of the heart the holy truths are to be written; so that if, in the business of life, the writing on the fingers may get blurred or effaced, the principles of righteousness may yet be kept like priceless archives stored in the inviolable chambers of the inner man. Wisdom is to be treated as a sister,[111] not as if there were a natural kinship, but on the ground of the beautiful influence which a true sister, a pure woman soul, exercises over a young man's life. It is given to a sister again and again, by unfailing sympathy and by sweet comprehending ways, not teasing nor lecturing, but always believing and hoping and loving, to weave a magical spell of goodness and truth around a brother who is exposed to dangerous temptations; she will "maintain for him a saving intercourse with his true self;" when the fires of more ardent affections are burning low, or extinguished in doubt or disgust, she will be with him like a calm impersonal presence, unobtrusive, unforgotten, the more potent because she makes no show of power. Such a lovely fraternal relation is to be maintained with Wisdom, constant as a tie of blood, firm as a companionship from earliest infancy, yet exalted and enthusiastic in its way, and promising a lifelong attraction and authority. This blessed kinship with Understanding should save the young man from such a fate as we are now to contemplate.
