Proverbs 20:18. Every purpose is established by counsel — “Rashness spoils the best designs, which must be carried on prudently, and with good advice, if we would have them to prove successful.” And with good advice make war — Warlike expeditions are not to be undertaken without great deliberation. It should be maturely considered, whether the war ought to be begun or not; whether it be just, whether it be prudent. And, when it is begun, how, and by what arts, it may be successfully prosecuted: for skill is as necessary as courage. Going to law is a kind of going to war, and therefore should not be done without good advice.

20:7. A good man is not liable to uneasiness in contriving what he shall do, or in reflecting on what he has done, as those who walk in deceit. And his family fare better for his sake. 8. If great men are good men, they may do much good, and prevent very much evil. 9. Some can say, Through grace, we are cleaner than we have been; but it was the work of the Holy Spirit. 10. See the various deceits men use, of which the love of money is the root. The Lord will not bless what is thus gotten. 11. Parents should observe their children, that they may manage them accordingly. 12. All our powers and faculties are from God, and are to be employed for him. 13. Those that indulge themselves, may expect to want necessaries, which should have been gotten by honest labour. 14. Men use arts to get a good bargain, and to buy cheap; whereas a man ought to be ashamed of a fraud and a lie. 15. He that prefers true knowledge to riches, follows the ways of religion and happiness. If we really believed this truth, the word of God would be valued as it deserves, and the world would lose its tempting influence. 16. Those ruin themselves who entangle themselves in rash suretiship. Also those who are in league with abandoned women. Place no confidence in either. 17. Wealth gotten by fraud may be sweet, for the carnal mind takes pleasure in the success of wicked devices; but it will be bitter in the reflection. 18. Especially we need advice in spiritual warfare. The word and Spirit of God are the best counsellors in every point. 19. Those dearly buy their own praise, who put confidence in a man because he speaks fairly. 20. An undutiful child will become very miserable. Never let him expect any peace or comfort. 21. An estate suddenly raised, is often as suddenly ruined. 22. Wait on the Lord, attend his pleasure, and he will protect thee."To eat gravel" was a Hebrew Lam 3:16, and is an Arabic, phrase for getting into trouble. So "bread," got by deceit, tastes sweet at first, but ends by leaving the hunger of the soul unsatisfied. There is a pleasure in the sense of cleverness felt after a hard bargain or a successful fraud, which must be met by bidding men look on the after consequences. 18. (Compare Pr 15:22). Be careful and considerate in important plans. Every purpose is established by counsel; the way to bring our purposes and desires to a good effect, is to manage them with serious consideration and good advice. And; or, therefore. This is necessary in every common undertaking, and much more in a thing of such high importance as war is.

Every purpose is established by counsel,.... Or "the thought" (f) of a man, everyone of them, what he has thought to do, formed a scheme of in his mind, and resolved upon, by taking advice of his friends, and especially by asking counsel of God, who gives, wisdom liberally, and upbraids not; he is confirmed in his good designs; and he cheerfully pursues them, and they are ordered and directed to the glory of God, his own good and the good of others; for this can only be understood of wise and good thoughts and purposes;

and with good advice make war; this should not be entered upon rashly, without first considering whether there is a just and lawful cause of it; and without consulting the necessary charge and expense of it; whether there is a sufficiency of men and money to carry it on; and what may probably be the issue of it. It is right in a king to advise with his privy council, or with the chief council of the nation; but, above all, both he and his people should seek advice of the Lord on such an occasion; see Luke 14:31. This may be applied to our spiritual warfare with sin, Satan, and the world; not that it should be any doubt with whether we should engage in such a war; but we should advise with experienced soldiers, and especially with God and his word, what weapons to take, and how to use them; and consider in whose name and strength we are to fight; and inquire and learn the force, methods, and designs of the enemy, and where to guard against them or attack them. Jarchi interprets it of making war with Satan by repentance, prayer, and fasting.
