Luke 11:30-31

In the same way Jonah became a sign to the people of Nineveh, so the Son of Man will be a sign to this generation. “The Queen of Sheba will rise up on the day of judgment to accuse and condemn this generation for its unbelief. She journeyed from a far and distant land just to listen to the wisdom of King Solomon. One greater than Solomon speaks with you today, but you refuse to listen.
