17 In the falling of thine enemy rejoice not, And in his  stumbling let not thy heart be joyful,
         
                                
                        18 Lest Jehovah see, and [it be] evil in His eyes, And He  hath turned from off him His anger.
         
                                
                        19 Fret not thyself at evil doers, Be not envious at the  wicked,
         
                                
                        20 For there is not a posterity to the evil, The lamp of the  wicked is extinguished.
         
                                
                        21 Fear Jehovah, my son, and the king, With changers mix not  up thyself,
         
                                
                        22 For suddenly doth their calamity rise, And the ruin of  them both -- who knoweth!
         
                                
                        23 These also are for the wise: --  To discern faces in  judgment is not good.
