Acts 10:4-15

4And when he looked on him, he was afraid, and said, What is it, Lord? And he said to him, Thy prayers and thy alms are come up for a memorial before God. 5And now send men to Joppa, and call for one Simon, whose surname is Peter: 6He lodgeth with one Simon a tanner, whose house is by the sea side: he shall tell thee what thou oughtest to do. 7And when the angel who spoke to Cornelius had departed, he called two of his household servants, and a devout soldier of them that waited on him continually; 8And when he had declared all these things to them, he sent them to Joppa.

9On the next day, as they were going on their journey, and drew near to the city, Peter went up upon the housetop to pray about the sixth hour: 10And he became very hungry, and would have eaten: but while they made ready, he fell into a trance, 11And saw heaven opened, and a certain vessel descending to him, as it had been a great sheet knit at the four corners, and let down to the earth: 12In which were all manner of fourfooted beasts of the earth, and wild beasts, and creeping things, and fowls of the air. 13And there came a voice to him, Rise, Peter; kill, and eat. 14But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean. 15And the voice spoke to him again the second time, What God hath cleansed, that call not thou common.
