Note, 1. Religion is true wisdom, and it makes men wise in every relation. He that conscientiously keeps the law is wise, and he will be particularly a wise son, that is, will act discreetly towards his parents, for the law of God teaches him to do so. 2. Bad company is a great hindrance to religion. Those that are companions of riotous men, that choose such for their companions and delight in their conversation, will certainly be drawn from keeping the law of God and drawn to transgress it, Psa 119:115. 3. Wickedness is not only a reproach to the sinner himself, but to all that are akin to him. He that keeps rakish company, and spends his time and money with them, not only grieves his parents, but shames them; it turns to their disrepute, as if they had not done their duty to him. They are ashamed that a child of theirs should be scandalous and abusive to their neighbours.

Whoso keepeth the law is a wise son,.... That observes the law of God; for, though he cannot perfectly keep it, yet he delights in it after the inward man; and with his spirit serves it, from a principle of love, in faith, and with a view to the glory of God, without mercenary and sinister ends. Such a man enjoys peace, and has a reward "in" though not "for" keeping the commands of it; so that it is his wisdom to observe it; and he may be truly called a wise man, Deu 4:6; Or that observes the law or commandments of his parents, which they enjoin him; see Pro 6:20; and particularly the law of God, which requires honour and obedience to be given to parents, and which turns to the account of children; it is well with them, and their days are prolonged on earth, and therefore they are wise that keep it, Eph 6:1; and such a wise son makes a glad father, as the contrary brings shame to him, as in the next clause;

but he that is a companion of riotous men shameth his father: that keeps company with gluttons, and indulges his sensual appetite with them; that "feeds" (d) such persons and himself, as some render the word; that gives up himself to an epicurean life: he brings himself at last to disgrace and poverty, and so causes shame to his father; who will be charged with neglecting his education, and indulging him in such a luxurious way of living; see Pro 10:5.
