Midrash for Kiddushin 32:20

(Devarim 15:13) "And when you send him free from yourself … (14) Bestow shall you bestow upon him …" I might think that the bestowal obtains only with one who lives after six years. Whence do we derive (that it similarly obtains) with one who leaves in Yovel, or upon the master's death, (in the instance of) a Hebrew maid-servant, with signs of puberty? From (the redundancy [12]) "you shall send him … And when you send him." "And when you send him": I might think that the bestowal obtains also with one who leaves by a monetary deduction (from his remaining years of service); it is, therefore, written "And when you send him free from yourself": (The bestowal obtains) with one whose being sent away is from yourself, and not from himself (i.e., from his own devices). (Ibid. 14).
