Proverbs 29:3

Whoso loveth wisdom rejoiceth his father: but he that keepeth company with harlots spendeth his substance.
– Proverbs 29:3

This saying echoes a long line of wisdom sayings pertaining to sons who acquire wisdom blessing their fathers (Proverbs 10:1; 15:20; 23:15, 24-25; 27:11). The second line gives the contrasting parallel for the foolish sons (Proverbs 5:8-10; 6:26; 21:17, 20; 28:7, 19). The contrast is between loving and pursuing wisdom or loving and pursuing folly. Wisdom and folly are personified as women in Proverbs (Proverbs 9:1-18), and so loving wisdom is pictured through finding a virtuous wife (Proverbs 31:10-31) and folly through chasing prostitutes (Proverbs 5:1-23; 7:1-27). Jesus told of such a foolish son, who went on to forsake folly for wisdom (Luke 15:11-32).
