Tosefta su Genesi 33:26

They put up animals in inns of Samaritans, even males in the places of females and females in the places of males, and it is unnecessary to say males in the places of males and females in the places of males. They give possession of an animal to their shepherd, and they give over their child to teach him book(s) and to teach him art and to be alone with him. A daughter of Israel (may) act as a midwife or a wet-nurse for a Samaritan woman and a Samaritan (woman may) act as a midwife or a wet-nurse for an Israelite woman. They do not put up an animal in inns of idol worshipers, not even males in the places of males or females in the places of females, as a male will have sexual relations with a male and a female will have sexual relations with a female, and it is unnecessary to say males in the places of females and females in the places of males. And they do not give possession of an animal to their shepherd, nor a child to teach him book(s) or to teach him art or to be alone with him. A daughter of Israel may not be a wet-nurse for the an idol worshiper because she raise him for idol worship; but an idol worshiper may act as a wet-nurse for an Israelite woman in her domain. A daughter of Israel may not act as a midwife for an idol worshiper because she delivers (the child) for idol worship. An idol worshiper may not act as a midwife for a daughter of Israel, because they suspect (idol worshipers) of (taking) lives, (these are) the words of Rabbi Meir. But the Sages say that an idol worshiper may act as a midwife for a daughter of Israel in a time when others stand over her, but when they are alone together, it is prohibited, because they suspect (idol worshipers) of (taking) lives. One may be treated by them (provided that it is) monetary treatment, but not personal treatment. An idol worshiper should not cut the embryo from the female organs of an Israelite woman, and she should not drink a cup of infertility potion, because they suspect (idol worshipers) of (taking) lives. An Israelite should not be alone with an idol worshiper, whether to bathe or in a bathhouse. An Israelite who encounters an idol worshiper on the road should (put the idol worshiper) to his right and not to his left. R. Yishmael ben R. Yohanan ben Beroqa says, (if the idol worshiper has) a sword, to his right. (If the idol worshiper has) a stick, to his left. (If) the two of them go up an incline or down a decline, the Israelite should stay above and the idol worshiper below. And he should not bend down before him, lest the idol worshiper break his skull. He should extend the journey (if an idol worshiper) asks him where he is going and divert him from the path, as it says Jacob did to Esau (Genesis 33): "until I come upon my lord at Seir," but he went to Sukkot. An Israelite may get a haircut from an idol worshiper (if) he can see in a mirror. (If) from a Samaritan, he does not need to look in a mirror. The house of Rabban Gamaliel permitted one to look in the mirror because they are in contact with the government. An Israelite who cuts the hair of idol worshiper, when he reaches the forelock, he should remove his hand.
