Thematic Bible: The sheet lowered down from the sky (in peter's vision)

And he became hungry and desired to eat. But as they were making ready an ecstasy came upon him: and he beholds the heaven opened, and a certain vessel descending, as a great sheet, bound by the four corners and let down to the earth; in which were all the quadrupeds and creeping things of the earth, and the fowls of the heaven. read more.
And there was a voice to him, Rise, Peter, slay and eat. And Peter said, In no wise, Lord; for I have never eaten anything common or unclean. And there was a voice again the second time to him, What God has cleansed, do not thou make common. And this took place thrice, and the vessel was straightway taken up into heaven.
