15 Lay not wait, O wicked one, At the habitation of the  righteous. Do not spoil his resting-place.
         
                                
                        16 For seven [times] doth the righteous fall and rise, And  the wicked stumble in evil.
         
                                
                        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,
