"If thou carriest thy wife with thee (and it is not well for those that administer governments to be long without their wives), teach and instruct her, and strive to smooth down her natural roughness; for all that may be gained by a wise governor may be lost and wasted by a boorish stupid wife.
"If perchance thou art left a widower — a thing which may happen — and in virtue of thy office seekest a consort of higher degree, choose not one to serve thee for a hook, or for a fishing-rod, or for the hood of thy 'won't have it;' for verily, I tell thee, for all the judge's wife receives, the husband will be held accountable at the general calling to account; where he will have repay in death fourfold, items that in life he regarded as naught.
"Never go by arbitrary law, which is so much favoured by ignorant men who plume themselves on cleverness.
"Let the tears of the poor man find with thee more compassion, but not more justice, than the pleadings of the rich.
"Strive to lay bare the truth, as well amid the promises and presents of the rich man, as amid the sobs and entreaties of the poor.
"When equity may and should be brought into play, press not the utmost rigour of the law against the guilty; for the reputation of the stern judge stands not higher than that of the compassionate.
"If perchance thou permittest the staff of justice to swerve, let it be not by the weight of a gift, but by that of mercy.
"If it should happen thee to give judgment in the cause of one who is thine enemy, turn thy thoughts away from thy injury and fix them on the justice of the case.
"Let not thine own passion blind thee in another man's cause; for the errors thou wilt thus commit will be most frequently irremediable; or if not, only to be remedied at the expense of thy good name and even of thy fortune.
"If any handsome woman come to seek justice of thee, turn away thine eyes from her tears and thine ears from her lamentations, and consider deliberately the merits of her demand, if thou wouldst not have thy reason swept away by her weeping, and thy rectitude by her sighs.
"Abuse not by word him whom thou hast to punish in deed, for the pain of punishment is enough for the unfortunate without the addition of thine objurgations.
"Bear in mind that the culprit who comes under thy jurisdiction is but a miserable man subject to all the propensities of our depraved nature, and so far as may be in thy power show thyself lenient and forbearing; for though the attributes of God are all equal, to our eyes that of mercy is brighter and loftier than that of justice.
"If thou followest these precepts and rules, Sancho, thy days will be long, thy fame eternal, thy reward abundant, thy felicity unutterable; thou wilt marry thy children as thou wouldst; they and thy grandchildren will bear titles; thou wilt live in peace and concord with all men; and, when life draws to a close, death will come to thee in calm and ripe old age, and the light and loving hands of thy great-grandchildren will close thine eyes.
"What I have thus far addressed to thee are instructions for the adornment of thy mind; listen now to those which tend to that of the body."
