פירוש על קידושין 30:7

The Talmud now offers a different reason for their dispute, which is anchored in the words of the verse. There are three forms of redemption alluded to in the verse—by relatives, by oneself, by strangers. Rabbi Yose Hagalili says that redemption by oneself teaches something about what appears before—redemption by relatives. Just as self-redemption is (obviously) for freedom, so is redemption by relatives. R. Akiva says that the verse teaches about that which follows. Just as redemption by oneself leads to freedom, so does redemption by others.
