Matthew Poole and continuators on Leviticus 27:20

20 And if he will not redeem the field , or if he have sold the field , to another man, it shall not be redeemed any more .

To wit, when the Priest shall set a price upon it, and offer it to him in the first place to redeem it.

He, who? Either 1. the man that vowed it, if he, after such a vow made shall neglect to pay his vow, and shall sacrilegiously sell the same land to another man: or, if he sell it, i. e. suffer it to be sold to another, and will not prevent that by redeeming it to himself. Or rather 2. the Priest, or some in his name, who though not expressed is sufficiently understood out of the foregoing clause, If he will not redeem or buy again the field, to wit, of the Priest, who is now the seller of it, or, or rather and, for this seems to be added by way of accumulation, if he, i. e. the Priest, of whom he might have redeemed it, upon his refusal, offers it to sale, and have sold the field to another man. Add to this, that none but the Priest could sell this land, after it was once vowed and declared to be so, and offered by the Priest to him again to redeem it, which is apparently the present case.

(i. e) He shall for ever lose the benefit of redemption.
