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.

A wise son maketh a glad father,.... See Gill on Pro 10:1;

but a foolish man despiseth his mother; that bore him and brought him up, and perhaps was too indulgent to him; which aggravates his sin and her sorrow; See Gill on Pro 10:1; or causes her to be despised by others, as Jarchi interprets it; such a man's sin, which is great folly, and shows him to be a foolish man, is highly resented by the Lord, and will be severely punished; see Pro 30:17. The Targum is,

"a foolish son despises his mother;''

and so the Septuagint, Syriac, and Arabic versions, which makes the antithesis more clear; and the Hebrew text designs one grown up to man's estate.

(Compare Pro 10:1).
