The Samaritans were Gentiles who had been settled in the land of Israel by the king of Assyria after the captivity which he made. They had been driven by many terrors to turn to Judaism, and had received circumcision and the five books of Moses, but renouncing everything else; hence there was no communication between the Jews and the Samaritans.
