John Gill's Exposition of the Whole Bible
Leviticus 27:21
But the field, when it goeth out in the jubilee,.... Out of the hand of him that bought it:
shall be holy unto the Lord, as a field devoted; though it went out of the hand of the purchaser, it did not return to him that sanctified or devoted it, but was separated to sacred uses for the service of the Lord; for every devoted thing, whether of man, beast, or field, was most holy to the Lord, Leviticus 27:28;
the possession thereof shall be the priests'; it did not return to the treasurer of the sanctuary, who had sold it to another for the repair of the temple, as Jarchi observes, but as a devoted field it was given to the priests, as it is said, "everything devoted in Israel shall be thine", Numbers 18:14; and even this was divided, as he says, between the priests of that ward or course that happened to be on the day of atonement of the jubilee year: but in case it never was redeemed, but remained sanctified in the year of jubilee, the priests did not possess it without paying for it; and so the Jewish canon runs c,
"the jubilee comes, and the field is not redeemed, the priests enter into it, and pay the price of it;''
on which one of the commentators d observes, when anyone has redeemed it, the money becomes sacred for the repairs of the temple; and when the jubilee comes, it goes out (i.e. of the hands of the purchaser) to the priests freely; but if it is not redeemed, the priests must pay the price of fifty shekels, and take it; and if even it was bought by a priest before out of the hands of the treasurer, it went from him to his brethren the priests, in the year of jubilee: the rule is this,
"if any of the priests redeem it, and, lo, it is in his possession, he may not say, seeing it goes out to the priests in the year of jubilee, lo, it is in my possession, lo, it is mine, but it shall go out to all his brethren the priests e.''
