When a master marries his slave to a free woman, places tefillin on his head, or tells him to read three verses from a Torah scroll in public, or the like - i.e., matters in which only a freed person is obligated - he is considered to be free. We compel his master to compose a bill of release for him. Similar rules apply when the slave took a vow that we compel slaves to fulfill, as we have stated with regard to vows, and instead of compelling him, his master said: "The vow is annulled." Since he did not compel him in a situation in which he should have compelled him, he indicated that he was concluding his subjugation of him. From this, I conclude that if a person frees a slave while speaking in any language and utters statements that indicate that his intent is that he does not retain any authority over him at all, and he has resolved to accept this step, he cannot retract. We compel him to write a bill of release even though he has not written one already. If, however, a person borrows money from his slave, makes him a guardian, the slave puts on tefillin in his master's presence, or reads three verses in the synagogue in his master's presence, and his master does not rebuke him, he does not obtain his freedom.
