We are tempted to envy those that grow rich, and raise their estates and families, by such unjust courses as our consciences will by no means suffer us to use. But, to set aside that temptation, Solomon here shows that a man, with prudent management, may raise his estate and family by lawful and honest means, with a good conscience, and a good name, and the blessing of God upon his industry; and, if the other be raised a little sooner, yet these will last a great deal longer. 1. That which is here recommended to us as having the best influence upon our outward prosperity is wisdom, and understanding, and knowledge; that is, both piety towards God (for that is true wisdom) and prudence in the management of our outward affairs. We must govern ourselves in every thing by the rules of religion first and then of discretion. Some that are truly pious do not thrive in the world, for want of prudence; and some that are prudent enough, yet do not prosper, because they lean to their own understanding and do not acknowledge God in their ways; therefore both must go together to complete a wise man. 2. That which is here set before us as the advantage of true wisdom is that it will make men's outward affairs prosperous and successful. (1.) it will build a house and establish it, Pro 24:3. Men may by unrighteous practices build their houses, but they cannot establish them, for the foundation is rotten (Hab 2:9, Hab 2:10); whereas what is honestly got will wear like steel and be an inheritance to children's children. (2.) It will enrich a house and furnish it, Pro 24:4. Those that manage their affairs with wisdom and equity, that are diligent in the use of lawful means for increasing what they have that spare from luxury and spend in charity, are in a fair way to have their shops, their warehouses, their chambers, filled with all precious and pleasant riches - precious because got by honest labour, and the substance of a diligent man is precious - pleasant because enjoyed with holy cheerfulness. Some think this is to be understood chiefly of spiritual riches. By knowledge the chambers of the soul are filled with the graces and comforts of the Spirit, those precious and pleasant riches; for the Spirit, by enlightening the understanding, performs all his other operations on the soul. (3.) It will fortify a house and turn it into a castle: Wisdom is better than weapons of war, offensive or defensive. A wise man is in strength, is in a strong-hold, yea, a man of knowledge strengthens might, that is, increases it, Pro 24:5. As we grow in knowledge we grow in all grace, Pe2 3:18. Those that increase in wisdom are strengthened with all might, Col 1:9, Col 1:11. A wise man will compass that by his wisdom which a strong man cannot effect by force of arms. The spirit is strengthened both for the spiritual work and the spiritual warfare by true wisdom. (4.) It will govern a house and a kingdom too, and the affairs of both, Pro 24:6. Wisdom will erect a college, or council of state. Wisdom will be of use, [1.] For the managing of the public quarrels, so as not to engage in them but for an honest cause and with some probability of success, and, when they are engaged in, to manage them well, and so as to make either an advantageous peace or an honourable retreat: By wise counsel thou shalt make war, which is a thing that may prove of ill consequence if not done by wise counsel. [2.] For the securing of the public peace: In the multitude of counsellors there is safety, for one may foresee the danger, and discern the advantages, which another cannot. In our spiritual conflicts we need wisdom, for our enemy is subtle.

Here is the description, 1. Of a weak man: Wisdom is too high for him; he thinks it so, and therefore, despairing to attain it, he will take no pains in the pursuit of it, but sit down content without it. And really it is so; he has not capacity for it, and therefore the advantages he has for getting it are all in vain to him. It is no easy thing to get wisdom; those that have natural parts good enough, yet if they be foolish, that is, if they be slothful and will not take pains, if they be playful and trifling, and given to their pleasures, if they be viciously inclined and keep bad company, it is too high for them; they are not likely to reach it. And, for want of it, they are unfit for the service of their country: They open not their mouth in the gate; they are not admitted into the council or magistracy, or, if they are, they are dumb statues, and stand for cyphers; they say nothing, because they have nothing to say, and they know that if they should offer any thing it would not be heeded, nay, it would be hissed at. Let young men take pains to get wisdom, that they may be qualified for public business, and do it with reputation. 2. Of a wicked man, who is not only despised as a fool is, but detested. Two sorts of wicked men are so: - (1.) Such as are secretly malicious. Though they speak courteously and conduct themselves plausibly, they devise to do evil, are contriving to do an ill turn to those they bear a grudge to, or have an envious eye at. He that does so shall be called a mischievous person, or a master of mischief, which perhaps was then a common name of reproach; he shall be branded as an inventor of evil things (Rom 1:30), or if any mischief be done, he shall be suspected as the author of it, or at least accessory to it. This devising evil is the thought of foolishness, Pro 24:9. It is made light of, and turned off with a jest, as only a foolish thing, but really it is sin, it is exceedingly sinful; you cannot call it by a worse name than to call it sin. It is bad to do evil, but it is worse to devise it; for that has in it the subtlety and poison of the old serpent. But it may be taken more generally. We contract guilt, not only by the act of foolishness, but by the thought of it, though it go no further; the first risings of sin in the heart are sin, offensive to God, and must be repented of or we are undone. Not only malicious, unclean, proud thoughts, but even foolish thoughts, are sinful thoughts. If vain thoughts lodge in the heart, they defile it (Jer 4:14), which is a reason why we should keep our hearts with all diligence, and harbour no thoughts there which cannot give a good account of themselves, Gen 6:5. (2.) Such as are openly abusive: The scorner, who gives ill-language to every body, takes a pleasure in affronting people and reflecting upon them, is an abomination to men; none that have any sense of honour and virtue will care to keep company with him. The seat of the scornful is the pestilential chair (as the Septuagint calls it, Psa 1:1), which no wise man will come near, for fear of taking the infection. Those that strive to make others odious do but make themselves so.
