"and on the seventh year he shall go out to freedom": What is the intent of this? From (Devarim 15:13) "And when you send him away, etc." I might think that he must write him a writ of emancipation; it is, therefore, written "he shall go out to freedom." Or I might think that he (the servant) must indemnify him; it is, therefore, written "he shall go out to freedom, gratis."
Sifra
acquire from the hand of your fellow, you shall not wrong, one man, his brother.") Whence is it derived that when you sell, you shall sell only to your fellow (Jew) (i.e., giving him first choice)? From "And if you sell a selling to your fellow." And whence is it derived that when you buy, you shall buy only from your fellow? From "or acquire from the hand of your fellow." This tells me only of land, of which Scripture is speaking (viz. Devarim 15:13). Whence do I derive (the same ["your fellow"] for) a movable object? From (the superfluous) "a selling" — to include a movable object. Whence is it derived that (the law of) ona'ah ("wronging") does not apply to land? From "or acquire from the hand … you shall not wrong" — ona'ah applies to a movable object, (which is transferred from hand to hand), but not to land.

Another interpretation, “you shall surely send away [shale’aḥ teshalaḥ]” – the Rabbis say: Why is this [verb written] twice? It is so that if this mitzva presents itself to you a second time, do not say: ‘I have already fulfilled my obligation.’ Instead, each time it presents itself to you, you must fulfill it.
Another interpretation, “you shall surely send away [shale’aḥ teshalaḥ]” – the Rabbis say: If you sent away [the mother in accordance with] the mitzva of the nest, you will be privileged to send away a Hebrew slave.11That is, you will be wealthy enough to purchase a Hebrew servant, who is freed at the end of seven years’ service. From where is this derived? It is as it is stated: “But when you send him free away from you” (Deuteronomy 15:13).
Another interpretation, “you shall surely send away [shale’aḥ teshalaḥ] the mother” – if you fulfil this mitzva, you will hasten the coming of the messianic king, in whose regard sending is written, as it is stated: “Who send out the foot of the bull and the donkey” (Isaiah 32:20).12The bull is an allusion to the proto-messianic king, a descendant of Joseph, in whose regard it is written: “A firstborn bull is his majesty” (Deuteronomy 33:17), and the donkey alludes to the messianic king, a descendant of David, in whose regard it is written: “Your king will come to you…he is humble, and riding on a donkey” (Zechariah 9:9).
Another interpretation [shale’aḥ teshalaḥ], Rabbi Tanḥuma said: If you fulfil this mitzva, you will hasten the coming of Elijah the prophet of blessed memory, in whose regard sending is written: “Behold, I am sending Elijah the prophet to you” (Malachi 3:23), and he will come and comfort you. From where is this derived? It is as it is written [of Elijah]: “He will restore the heart of parents with children” (Malachi 3:24).
