"Oh, what can I compare this generation with? They're like children sitting in the marketplaces, calling out to each other,
`We made happy music, but you wouldn't dance! We made sad music, but you wouldn't cry!'
For Yochanan came, fasting, not drinking -- so they say, `He has a demon.'
The Son of Man came, eating freely and drinking wine -- so they say, `Aha! A glutton and a drunkard! A friend of tax-collectors and sinners!' Well, the proof of wisdom is in the actions it produces."

"Woe to you, Korazin! Woe to you, Beit-Tzaidah! Why, if the miracles done in you had been done in Tzor and Tzidon, they would long ago have put on sackcloth and ashes as evidence that they had changed their ways.
But I tell you it will be more bearable for Tzor and Tzidon than for you on the Day of Judgment!
And you, K'far-Nachum, will you be exalted to heaven? No, you will be brought down to Sh'ol!b For if the miracles done in you had been done in S'dom, it would still be in existence today.
But I tell you that on the Day of Judgment it will be more bearable for the land of S'dom than for you!"
