Midrasch zu Bamidbar 35:28

4) "And he shall return to his family, and to the holding of his fathers shall he return." R. Eliezer b. R. Yaakov said: Of whom is Scripture speaking? If of a nirtza (one who elected life-long servitude), this has already been mentioned. If of one who sold himself, this has (also) been mentioned. It must be speaking, then, of one who was sold by beth-din one or two years before the Yovel, as subject to release by the Yovel. Variantly: "And he shall return to his family and to the holding of his fathers shall he return": He returns to the office that he held in his family. These are the words of R. Meir. R. Yehudah says: To his holding and to his family he returns, but he does not return to the office that he held in his family. And the same applies to one who was exiled (to the cities of refuge, viz. Bamidbar 35:28). "shall he return": to include a murderer (in the emancipation of Yovel.)

5) "And you shall return a man to his possession, and a man to his family you shall return.": R. Eliezer b. Yaakov said; Of whom is this stated? If of one who sold himself (into servitude), this has already been stated. If of one who was sold by beth-din, this has already been stated; and if of one who was sold by beth-din, the law in respect to this has also been stated. It must be speaking, then, of one who impressed himself into perpetual servitude by having his ear bored (as a sign of submission three or four years) before Yovel, (Scripture telling us) that Yovel releases him from his bondage. "and a man to his family you shall return": to the office that he held in his family. These are the words of R. Meir. R. Yehudah says: To his holding and to his family he returns, but he does not return to the office that he held in his family. And the same applies to one who was exiled (to the cities of refuge, viz. Bamidbar 35:28). "you shall return" (superfluous): to include a woman (sold by her father as a maid-servant in the emancipation of Yovel).
