'Common or Unclean' in the Bible

But Peter said: By no means, Lord; for I have never eaten any thing common or unclean.

And he said to them: You know that it is unlawful for a Jew to associate with one of another nation, or to go into his house. But God has showed me that I must not call any man common or unclean.

But I said, By no means, Lord; for nothing common or unclean has ever entered my mouth.
