Proverbs 29:3

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 Proverbs 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 Luke 15:13; and such a son grieves his father, seeing he spends his substance and damns his soul.
