Acts 10:9-15 On the next day, as they were on their way and approaching the city, Peter went up on the housetop about the sixth hour to pray. But he became hungry and was desiring to eat; but while they were making preparations, he fell into a trance; and he saw the sky opened up, and an object like a great sheet coming down, lowered by four corners to the ground, and there were in it all kinds of four-footed animals and crawling creatures of the earth and birds of the air. A voice came to him, “Get up, Peter, kill and eat!” But Peter said, “By no means, Lord, for I have never eaten anything unholy and unclean.” Again a voice came to him a second time, “What God has cleansed, no longer consider unholy.” This happened three times, and immediately the object was taken up into the sky.
Acts 10:28 "And he said to them, “You yourselves know how unlawful it is for a man who is a Jew to associate with a foreigner or to visit him; and yet God has shown me that I should not call any man unholy or unclean."
