If thou be wise - It is thy own interest to be religious. Though thy example may be very useful to thy neighbors and friends, yet the chief benefit is to thyself. But if thou scorn - refuse to receive - the doctrines of wisdom, and die in thy sins, thou alone shalt suffer the vengeance of an offended God.
The great law of personal retribution (compare Matthew 7:2). The Septuagint makes a curious addition to this verse, “My son, if thou wilt be wise for thyself, thou shalt be wise also for thy neighbors; but if thou turn out evil, thou alone shalt bear evil. He who resteth on lies shall guide the winds, and the same shall hunt after winged birds, for he hath left the ways of his own vineyard, and has gone astray with the wheels of his own husbandry. He goeth through a wilderness without water, and over a land set in thirsty places, and with his hands he gathereth barrenness.”
