29 As the crowds increased, Jesus said, “This is a wicked generation. It asks for a sign, but none will be given it except the sign of Jonah. 30 For as Jonah was a sign to the Ninevites, so also will the Son of Man be to this generation. 31 The Queen of the South will rise at the judgment with the people of this generation and condemn them, for she came from the ends of the earth to listen to Solomon’s wisdom; and now something greater than Solomon is here. 32 The men of Nineveh will stand up at the judgment with this generation and condemn it, for they repented at the preaching of Jonah; and now something greater than Jonah is here.
The ability to speak is a short cut to distinction. It puts a man in the limelight, raises him head and shoulders above the crowd.
