15 My son, if thy heart hath been wise, My heart rejoiceth,  even mine,
         
                                
                        16 And my reins exult when thy lips speak uprightly.
         
                                
                        17 Let not thy heart be envious at sinners, But -- in the  fear of Jehovah all the day.
         
                                
                        18 For, is there a posterity? Then thy hope is not cut off.
         
                                
                        19 Hear thou, my son, and be wise, And make happy in the way  thy heart,
         
                                
                        20 Be not thou among quaffers of wine, Among gluttonous ones  of flesh,
         
                                
                        21 For the quaffer and glutton become poor, And drowsiness  clotheth with rags.
