John Gill Commentary Leviticus 25:24

"And in all the land of your possession ye shall grant a redemption for the land." — Leviticus 25:24 (ASV)

And in all the land of your possession Which they should possess in the land of Canaan, whatever part of it any of them should enjoy:

you shall grant a redemption for the land ; that is, whenever any estate in it was sold through necessity, the buyer was obliged to grant a liberty to the seller to redeem it, when it was in his power to do it, or any or his relations, especially after two years; so Jarchi observes, he that sells his possession may redeem it after two years, either he himself or he that is near akin to him, nor can the buyer hinder it; (See Gill on Leviticus 25:15).
