Acts 11:4-12 (NIV)
4 Starting from the beginning, Peter told them the whole story: 5 “I was in the city of Joppa praying, and in a trance I saw a vision. I saw something like a large sheet being let down from heaven by its four corners, and it came down to where I was. 6 I looked into it and saw four-footed animals of the earth, wild beasts, reptiles and birds. 7 Then I heard a voice telling me, ‘Get up, Peter. Kill and eat.’
8 “I replied, ‘Surely not, Lord! Nothing impure or unclean has ever entered my mouth.’
9 “The voice spoke from heaven a second time, ‘Do not call anything impure that God has made clean.’ 10 This happened three times, and then it was all pulled up to heaven again.
11 “Right then three men who had been sent to me from Caesarea stopped at the house where I was staying. 12 The Spirit told me to have no hesitation about going with them. These six brothers also went with me, and we entered the man’s house.
