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

and he became very hungry, and wished to eat; and they making ready, there fell upon him a trance, and he doth behold the heaven opened, and descending unto him a certain vessel, as a great sheet, bound at the four corners, and let down upon the earth, in which were all the four-footed beasts of the earth, and the wild beasts, and the creeping things, and the fowls of the heaven, read more.
and there came a voice unto him: 'Having risen, Peter, slay and eat.' And Peter said, 'Not so, Lord; because at no time did I eat anything common or unclean;' and there is a voice again a second time unto him: 'What God did cleanse, thou, declare not thou common;' and this was done thrice, and again was the vessel received up to the heaven.
