Acts 10:11-15

And saw heaven opened, and a certain vessel descending unto him, as it had been a great sheet knit at the four corners, and let down to the earth:

Wherein were all manner of fourfooted beasts of the earth, and wild beasts, and creeping things, and fowls of the air.

And there came a voice to him, Rise, Peter; kill, and eat.

But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean.

And the voice spake unto him again the second time, What God hath cleansed, that call not thou common.
