Proverbs 17:6 - Joseph Benson’s Commentary on the Old and New Testaments

Children's children are the crown of old men It is an honour to parents, when they are old, to leave children, and children's children growing up, that tread in the steps of their virtues, and are likely to maintain and advance the reputation of their families, and to serve their generation according to the will of God; and the glory of children are their fathers Namely, fathers that are wise and godly. To have such parents is an honour to children, and to have them continued to them even after they are themselves grown up, and settled in the world. Those are unnatural children indeed who reckon their aged parents a burden to them, and think they live too long; whereas, if children be wise and good, it is their greatest honour, that thereby they are comforts to their parents in the unpleasant days of their old age.
