Charles Ellicott Commentary Proverbs 19:10

"Delicate living is not seemly for a fool; Much less for a servant to have rule over princes." — Proverbs 19:10 (ASV)

Delight is not seemly for a fool.— He is ruined by prosperity and luxury: much more is a slave unfit to rule over princes. The writer has in mind the case of an emancipated slave being raised to high office by court favour, and then insolently trampling on those who were once far above him. (Ecclesiastes 10:6–7.)
