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

And he became very hungry, and would have eaten: but while they made ready, he fell into a trance, And saw heaven opened, and a certain vessel descending unto him, as it had been a great sheet held at the four corners, and let down to the earth: In which were all manner of four-footed beasts of the earth, and wild beasts, and creeping things, and fowls of the air. read more.
And there came a voice to him, Rise, Peter; kill, and eat. But Peter said, Not so, Lord; for I have never eaten anything that is common or unclean. And the voice spoke unto him again the second time, What God has cleansed, that call not common. This was done three times: and the vessel was received up again into heaven.
