Mishle 19:8-10

Orthodox Jewish Bible

⁸ He that getteth lev [of understanding] loveth his own nefesh; he that is shomer over tevunah (understanding) shall find tov.

⁹ An ed shekarim (false witness) shall not go unpunished, and he that speaketh kezavim (lies) shall perish.

¹⁰ Luxury is not fitting for a kesil (fool); much less for an eved to have rule over sarim.
