'Common or Unclean' in the Bible

But Peter said - By no means, Lord! because, at no time, have I eaten anything common or unclean.

And said unto the - Ye, well know, how unlawful it is, for, a Jew, to be joining himself or coming in unto one of another race. And yet, unto me, hath God pointed out that I should be calling no man, common or unclean.

But I said - By no means, Lord, because, a common or unclean thing, hath at no time entered into my mouth.
