15 Gold is not given for it, Nor is silver weighed -- its  price.
         
                                
                        16 It is not valued with pure gold of Ophir, With precious  onyx and sapphire,
         
                                
                        17 Not equal it do gold and crystal, Nor [is] its exchange a  vessel of fine gold.
         
                                
                        18 Corals and pearl are not remembered, The acquisition of  wisdom [is] above rubies.
         
                                
                        19 Not equal it doth the topaz of Cush, With pure gold it is  not valued.
         
                                
                        20 And the wisdom -- whence doth it come? And where [is]  this, the place of understanding?
         
                                
                        21 It hath been hid from the eyes of all living. And from the  fowl of the heavens It hath been hidden.
