Matthew Henry commentary on Proverbs 13:18-21
Embedded KJV/source Scripture
20 He that walketh with wise men shall be wise: but a companion of fools shall be destroyed.
Note, 1. Those that would be good must keep good company, which is an evidence for them that they would be good (men's character is known by the company they choose) and will be a means of making them good, of showing them the way and of quickening and encouraging them in it. He that would be himself wise must walk with those that are so, must choose such for his intimate acquaintance, and converse with them accordingly; must ask and receive instruction from them, and keep up pious and profitable talk with them. Miss not the discourse of the elders, for they also learned of their fathers, Ecclesiasticus viii. 9. And ( Ecclesiasticus vi. 35 ), Be willing to hear every godly discourse, and let not the parables of understanding escape thee. 2. Multitudes are brought to ruin by bad company: A companion of fools shall be broken (so some), shall be known (so the LXX.), known to be a fool; noscitur ex socio—he is known by his company. He will be like them (so some), will be made wicked (so others); it comes all to one, for all those, and those only, that make themselves wicked, will be destroyed, and those that associate with evil-doers are debauched, and so undone, and at last ascribe their death to it.

21 Evil pursueth sinners: but to the righteous good shall be repayed.
Here see, 1. How unavoidable the destruction of sinners is; the wrath of God pursues them, and all the terrors of that wrath: Evil pursues them closely wherever they go, as the avenger of blood pursued the manslayer, and they have no city of refuge to flee to; they attempt an escape, but in vain. Whom God pursues he is sure to overtake. They may prosper for a while and grow very secure, but their damnation slumbers not, though they do. 2. How indefeasible the happiness of the saints is; the God that cannot lie has engaged that to the righteous good shall be repaid. They shall be abundantly recompensed for all the good they have done, and all the ill they have suffered, in this world; so that, though many have been losers for their righteousness, they shall not be losers by it. Though the recompence do not come quickly, it will come in the day of payment, in the world of retribution; and it will be an abundant recompence.

22 A good man leaveth an inheritance to his children's children: and the wealth of the sinner is laid up for the just.
See here, 1. How a good man's estate lasts: He leaves an inheritance to his children's children. It is part of his praise that he is thoughtful for posterity, that he does not lay all out upon himself, but is in care to do well for those that come after him, not by withholding more than is meet, but by a prudent and decent frugality. He trains up his children to this, that they may leave it to their children; and especially he is careful, both by justice and charity, to obtain the blessing of God upon what he has, and to entail that blessing upon his children, without which the greatest industry and frugality will be in vain: A good man, by being good and doing good, by honouring the Lord with his substance and spending it in his service, secures it to his posterity; or, if he should not leave them much of this world's goods, his prayers, his instructions, his good example, will be the best entail, and the promises of the covenant will be an inheritance to his children's children, Ps. ciii. 17 . 2. How it increases by the accession of the wealth of the sinner to it, for that is laid up for the just. If it be asked, How should good men grow so rich, who are not so eager upon the world as others are and who commonly suffer for their well-doing? It is here answered, God, in his providence, often brings into their hands that which wicked people had laid up for themselves. The innocent shall divide the silver, Job xxvii. 16, 17 . The Israelites shall spoil the Egyptians ( Exod. xii. 36 ) and eat the riches of the Gentiles, Isa. lxi. 6 .

23 Much food is in the tillage of the poor: but there is that is destroyed for want of judgment.
See here, 1. How a small estate may be improved by industry, so that a man, by making the best of every thing, may live comfortably upon it: Much food is in the tillage of the poor, the poor farmers, that have but a little, but take pains with that little and husband it well. Many make it an excuse for their idleness that they have but a little to work on, a very little to be doing with; but the less compass the field is of the more let the skill and labour of the owner be employed about it, and it will turn to a very good account. Let him dig, and he needs not beg. 2. How a great estate may be ruined by indiscretion: There is that has a great deal, but it is destroyed and brought to nothing for want of judgment, that is, prudence in the management of it. Men over-build themselves or over-buy themselves, keep greater company, or a better table, or more servants, than they can afford, suffer what they have to go to decay and do not make the most of it; by taking up money themselves, or being bound for others, their estates are sunk, their families reduced, and all for want of judgment.
