Matthew Henry commentary on Proverbs 21:17-20
Embedded KJV/source Scripture
19 It is better to dwell in the wilderness, than with a contentious and an angry woman.
Note, 1. Unbridled passions embitter and spoil the comfort of all relations. A peevish angry wife makes her husband's life uneasy, to whom she should be a comfort and a meet help. Those cannot dwell in peace and happiness that cannot dwell in peace and love. Even those that are one flesh, if they be not withal one spirit, have no joy of their union. 2. It is better to have no company than bad company. The wife of thy covenant is thy companion, and yet, if she be peevish and provoking, it is better to dwell in a solitary wilderness, exposed to wind and weather, than in company with her. A man may better enjoy God and himself in a wilderness than among quarrelsome relations and neighbours. See v. 9 .

20 There is treasure to be desired and oil in the dwelling of the wise; but a foolish man spendeth it up.
Note, 1. Those that are wise will increase what they have and live plentifully; their wisdom will teach them to proportion their expenses to their income and to lay up for hereafter; so that there is a treasure of things to be desired, and as much as needs be desired, a good stock of all things convenient, laid up in season, and particularly of oil, one of the staple commodities of Canaan, Deut. viii. 8 . This is in the habitation, or cottage, of the wise; and it is better to have an old-fashioned house, and have it well furnished, than a fine modern one, with sorry housekeeping. God blesses the endeavors of the wise and then their houses are replenished. 2. Those that are foolish will misspend what they have upon their lusts, and so bring the stock they have to nothing. Those manage wretchedly that are in haste to spend what they had, but not in care which way to get more. Foolish children spend what their wise parents have laid up. One sinner destroys much good, as the prodigal son.

21 He that followeth after righteousness and mercy findeth life, righteousness, and honour.
See here, 1. What it is to make religion our business; it is to follow after righteousness and mercy, not to content ourselves with easy performances, but to do our duty with the utmost care and pains, as those that are pressing forward and in fear of coming short. We must both do justly and love mercy, and must proceed and persevere therein; and, though we cannot attain to perfection, yet it will be a comfort to us if we aim at it and follow after it. 2. What will be the advantage of doing so: Those that do follow after righteousness shall find righteousness; God will give them grace to do good, and they shall have the pleasure and comfort of doing it; those that make conscience of being just to others shall have the pleasure and comfort of doing it; those that make conscience of being just to others shall be justly dealt with by others and others shall be kind to them. The Jews followed after righteousness, and did not find it, because they sought amiss, Rom. ix. 31 . Otherwise, Seek and you shall find, and with it shall find both life and honour, everlasting life and honour, the crown of righteousness.

22 A wise man scaleth the city of the mighty, and casteth down the strength of the confidence thereof.
Note, 1. Those that have power are apt to promise themselves great things from their power. The city of the mighty thinks itself impregnable, and therefore its strength is the confidence thereof, what it boasts of and trust in, bidding defiance to danger. 2. Those that have wisdom, though they are so modest as not to promise much, often perform great things, even against those that are so confident of their strength, by their wisdom. Good conduct will go far even against great force; and a stratagem, well managed, may effectually scale the city of the mighty and cast down the strength it had such a confidence in. A wise man will gain upon the affections of people and conquer them by strength of reason, which is a more noble conquest than that obtained by strength of arms. Those that understand their interest will willingly submit themselves to a wise and good man, and the strongest walls shall not hold out against him.
