Avodah Zarah, Chapter Two, Mishnah Two
This mishnah is a continuation of the discussion which began in the previous mishnah. It continues to discuss prohibitions that are a result of the Jewish suspicion that non-Jews are murderers.
1) We may allow them to heal us when the healing relates to money, but not personal healing;
2) Nor should we have our hair cut by them in any place, this is the opinion of Rabbi Meir.
a) But the Sages said: in a public place it is permitted, but not when the two persons are alone.
Section one: A Jew is permitted to be healed by a non-Jew when the healing relates to money. In the Talmud this clause is explained to mean that a Jew may take his animals to a non-Jewish doctor. This healing is considered to be related to money because the animal is the Jews property. However, a Jew may not himself be healed by a non-Jewish doctor, lest the non-Jewish doctor purposefully cause him damage. The Talmud adds that if the non-Jewish doctor tells him that a certain drug would be beneficial he may listen to him, since the Jew could check this information with others.
Section two: According to Rabbi Meir a Jew may never get his hair cut by a non-Jew, lest the non-Jew kill him with the scissors or razor. The Sages say that this is only prohibited in private. In public the non-Jew would not dare to kill the Jew.
