2,169. Converting a Servant
Hilchos Issurei Biah 14:9
When a servant is purchased from non-Jews, we don’t ask why he has chosen to convert. Rather, we ask if he wants to be a Jewish servant and become observant. If he agrees, he is told about the basics of Judaism, about some of the easy mitzvos and some of the more difficult ones, and the punishments for violating and rewards for keeping the mitzvos, the same as we tell a convert. We immerse him as we do a convert, informing him of the mitzvos again while he’s in the water. If he chooses not to accept the mitzvos, we are patient with him for twelve months, after which he is sold to a non-Jew; it is prohibited to keep him any longer. If he made a condition that he wouldn’t be circumcised or immersed but that he would be a ger toshav (resident alien), it is permitted to keep him as such, though only at a time when the Jubilee is observed.
Hilchos Issurei Biah 14:10
The only sexual relationships prohibited to a non-Jew are his mother, his father’s wife (i.e., his stepmother), a sister sharing the same mother, a married woman, another male and an animal; this will be covered IY”H in Hilchos Melachim. Other relationships that are prohibited to Jews are permitted to non-Jews.
