Acts 10:13-16

A voice came to him, “Get up, Peter, kill and eat!” But Peter said, “Not at all, Lord, for I have never eaten anything that is common (unholy) and [ceremonially] unclean.” And the voice came to him a second time, “What God has cleansed and pronounced clean, no longer consider common (unholy).” This happened three times, and then immediately the object was taken up into heaven.
