Albert Barnes Commentary Proverbs 29:3

"Whoso loveth wisdom rejoiceth his father; But he that keepeth company with harlots wasteth [his] substance." — Proverbs 29:3 (ASV)

Spends ... - The laws of parallelism would lead us to expect “troubleth his father,” but that is passed over as a thing about which the profligate would not care, and he is reminded of what comes home to him, that he is on the road to ruin.

The king - The ruler, as the supreme fountain of all justice, and as the ideal judge, is contrasted with the taker of bribes.
