'Common or Unclean' in the Bible

But Peter said, "No, no, my Lord; I have never eaten anything common or unclean."

To them Peter said, "You know yourselves it is illegal for a Jew to join or accost anyone belonging to another nation; but God has shown me that I must not call any man common or unclean,

I said, 'No, no, my Lord; nothing common or unclean has ever passed my lips.'
