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.
