Both the parts of this verse repeat what has been often said, but, on comparing them together, the sense of them will be enlarged from each other. 1. Be it observed, to the honour of a virtuous young man, that he loves wisdom, he is a philosopher (for that signifies a lover of wisdom), for religion is the best philosophy; he avoids bad company, and especially the company of lewd women. Hereby he rejoices his parents, and has the satisfaction of being a comfort to them, and increases his estate, and is likely to live comfortably. 2. Be it observed, to the reproach of a vicious young man, that he hates wisdom; he keeps company with scandalous women, who will be his ruin, both in soul and body; he grieves his parents, and, like the prodigal son, devours their living with harlots. Nothing will beggar men sooner than the lusts of uncleanness; and the best preservative from those ruinous lusts is wisdom.

Whoso loveth wisdom rejoiceth his father,.... He that is a philosopher, especially a religious one, that not only loves and seeks after natural wisdom, but moral wisdom and knowledge; and more particularly evangelical wisdom, Christ the Wisdom of God, who is to be valued and loved above all things; the Gospel of Christ, which is the wisdom of God in a mystery; and the knowledge of it which is the wisdom which comes from above and is pure and peaceable; and which lies much in the fear of God, and in the faith of Jesus Christ, attended with all the fruits of righteousness: such a son makes glad his father, both because of his temporal good, since he does not waste but improve the substance he has given him; and because of his spiritual and eternal welfare; and since instead of being a reproach he is an honour to him; see Pro 10:1;

but he that keepeth company with harlots spendeth his substance: his father has given him, and comes to want and beggary; all which is a grief to his parents: or, "that feeds harlots" (i); who live in a riotous and voluptuous manner, and soon drain a man of his substance, and bring him to a morsel of bread; see Luk 15:13; and such a son grieves his father, seeing he spends his substance and damns his soul.
