Moses
Leviticus 25:49ESV·traditional attribution

or his uncle or his cousin may redeem him, or a close relative from his clan may redeem him. Or if he grows rich he may redeem himself.

Matthew Henry Presbyterian

We have here the laws concerning servitude, designed to preserve the honour of the Jewish nation as a free people, and rescued by a divine power out of the house of bondage, into the glorious liberty of God's sons, his first-born. Now the law is, I. That a native Israelite should never be made a bondman for perpetuity.

Commenting on Leviticus 25:39-55

John Gill Reformed Baptist

Either his uncle, or his uncle's son, may redeem him,.... it is father's brother or his father's brother's son, as the Targums of Onkelos and Jonathan: or any that is nigh kin unto him of his family may redeem him; from whence it appears, that it must be a near kinsman that has to be the redeemer, as in another case, the redemption of inheritances...

Geneva Bible Notes Reformed

Either his uncle, or his uncle's son, may redeem him, or [any] that is nigh of kin unto him of his family may redeem him; or if he be able, he may redeem himself. (u) If he be able.
