'Common or Unclean' in the Bible

But Peter said, In no wise, Lord: for I have never eaten any thing common or unclean.

And he said to them, Ye know it is unlawful for a Jew to join with or come to one of another nation; but God hath shewed me, to call no man common or unclean.

But I said, In no wise, Lord: for nothing common or unclean hath ever entered into my mouth.
