A wise son maketh a glad father: but a foolish man despiseth his mother.

Matthew Henry's Concise Commentary

15:16,17. Believers often have enough when worldly eyes see little; the Lord is with them, without the cares, troubles, and temptations which are with the wealth of the wicked. 18. He that is slow to anger, not only prevents strife, but appeases it, if kindled. 19. Those who have no heart to their work, pretend that they cannot do their work without hardship and danger. And thus many live always in doubt about their state, because always in neglect of some duty. 20. Those who treat an aged mother or a father with contempt or neglect, show their own folly. 21. Such as are truly wise, study that their thoughts, words, and actions should be regular, sincere, and holy. 22. If men will not take time and pains to deliberate, they are not likely to bring any thing to pass. 23. Wisdom is needed to suit our discourse to the occasions. 24. A good man sets his affections on things above; his way leads directly thither.

Matthew Henry's Whole Bible Commentary

Verse 20

Observe here, 1. To the praise of good children, that they are the joy of their parents, who ought to have joy of them, having taken so much care and pains about them. And it adds much to the satisfaction of those that are good if they have reason to think that they have been a comfort to their parents in their declining years, when evil days come. 2. To the shame of wicked children, that by their wickedness they put contempt upon their parents, slight their authority, and make an ill requital for their kindness: A foolish son despises his mother, that had most sorrow with him and perhaps had too much indulged him, which makes his sin in despising her the more sinful and her sorrow the more sorrowful.
