That is that He commanded us that the master who acquired a Hebrew (Jewish) maidservant marry her - [he] or his son. And that is the commandment of designation [that] has precedence over the commandment of redemption, by His saying, "who designated her for himself, he must let her be redeemed" (Exodus 21:8). But you should know that the law of a Hebrew slave and a Hebrew maidservant are only practiced at the time that the Jubilee is practiced. And the regulations of this commandment have already been explained in Chapter 4 of Tractate Kiddushin.
