Luke 11:27

The unclean spirit, when he has gone out of the man, passes through dry places, seeking rest; and finding none, he says, ‘I will turn back to my house from which I came out.’

When he returns, he finds it swept and put in order.

Then he goes and takes seven other spirits more evil than himself, and they enter in and dwell there. The last state of that man becomes worse than the first.”

But he said, “On the contrary, blessed are those who hear the word of God, and keep it.”

When the multitudes were gathering together to him, he began to say, “This is an evil generation. It seeks after a sign. No sign will be given to it but the sign of Jonah the prophet.

For even as Jonah became a sign to the Ninevites, so the Son of Man will also be to this generation.
