Matthew Poole and continuators on Acts 10:28

28 And he said unto them, Ye know how that it is an unlawful thing for a man▪ that is a Jew , to keep company with, or come unto one of another nation : but▪ God hath shewed me, that I should not call any man common or unclean.

God himself did erect a partition-wall betwixt his people, and other Nations, Iews and Gentiles; hence by Gods own command, the Iews might not have any familiar converse with the Gentiles, especially, they might not marry with them: The Iews themselves had made this partition-wall much larger, and they held it unlawful to eat with any of the Gentiles, or to go so much as into their houses; hence that objection made upon this occasion against St. Peter, Chap. 11.3.

No man is now unclean by any ceremonial uncleanness, because he is not circumcised, or because he is not sprinkled with the blood of bulls, Hebr. 9.13. yet sin hath defiled the whole mass of man kind, and they are equally by nature morally unclean.
