Again, a second time, a voice said to him, “What God has made clean, you must not call common.”

But a voice answered from heaven a second time, ‘What God has made clean, you must not call common.’

But when they resisted and blasphemed, he shook his robe and told them, “Your blood is on your own heads! I am innocent. From now on I will go to the Gentiles.”
