Luke 11:30-32

Luke 11:30-32

[30] For  as  Jonas  was  a sign  unto the Ninevites,  so  also  the Son  of man  generation.  [31] The queen  of the south  shall rise up  in  the judgment  with  the men  generation,  and  condemn  them:  for  she came  from  the utmost parts  of the earth  to hear  the wisdom  of Solomon;  and,  behold,  a greater than  Solomon  is here.  [32] The men  shall rise up  in  the judgment  with  generation,  and  shall condemn  it:  for  they repented  at  the preaching  of Jonas;  and,  behold,  a greater than  Jonas  is here.
