Mishlĕ (Proverbs) 24:17-22

Do not exult when your enemy falls, And let not your heart rejoice when he stumbles; Lest יהוה see and it be evil in His eyes, And He turn away His wrath from him. Do not fret because of evil-doers, And do not envy the wrong; For there is no future for the evil-doer; The lamp of the wrongdoers is put out. My son, fear יהוה and the sovereign; Do not mingle with those who change; For their calamity arises suddenly, And who knows the ruin of both of them?
