Halakhah к Бамидбар 18:14

From the laws of the commandment is that which they, may their memory be blessed, said (Arakhin 28b), "What [is the difference] between dedications of the priests and dedications of the Heavens? That dedications of the Heavens are consecrated and are redeemed with their worth, their value goes to the [Temple] upkeep and the properties go out to the non-sacred. But the dedications of the priests" - meaning to say, an undifferentiated dedication, that [goes] to the priests - "never have redemption, but are rather given to the priests like priestly tithe." And it is concerning the dedications of the priests that it is stated, "it shall not be sold and it shall not be redeemed" (Leviticus 27:28) - "it shall not be sold" to another, "and it shall not be redeemed" for its [original] owners. It is one whether he dedicates land or movable items - they are given to the priests of that shift, [serving] at the time that he dedicates. And during the whole time that the dedications of the priests are in the house of the owners, they are consecrated for all of their purposes - as it is stated (Leviticus 27:28), "every dedication is holy of holies to the Lord." [Once] they are given to the priest, behold they are like the non-sacred for all of their purposes - as it is stated (Numbers 18:14), "Every dedication in Israel shall be for you." And a field that is dedicated to a priest never returns to the original owners. And the rest of its details are in the eight chapter of Arakhin and the first of Nedarim (see Mishneh Torah, Laws of Appraisals and Devoted Property 6).

That owners that dedicated land not sell it, but that it rather be given to the priests: That one should not sell a dedicated field, and so [too,] all other lands. And the law is the same for movable items that have been dedicated by their owners. Rather, they should be given to the priests of that watch, as we wrote in this Order, positive commandment 6 (Sefer HaChinukh 357). And it is even forbidden for the owners to sell it to the treasurer of the consecrated, but rather [the latter] should attain the rights to it with nothing. As God gave the rights of dedications to the priests. And this is with undifferentiated dedications, as we said above. Since it established for us [that the law is] like the [opinion] that says, undifferentiated dedications - meaning to say that one who dedicated but did not specify to whom - are for the priests. As if he dedicates explicitly for the upkeep of the [Temple], the priests do not get rights to [it]. And about the dedications of the priests is it stated here (Leviticus 27:28), "any dedication [...] shall not be sold." But the priests can certainly sell them according to their will. As [with] the dedications of the priests - after they have gone out from the hand of their owners who dedicated them and have reached the hand of the priests - behold they are like the non-sacred for all of their purposes, as it is stated (Numbers 18:14), "Every dedication in Israel shall be for you." But so long as they are still under the hand of the owners, it is stated about them (Leviticus 27:28), "every dedication is holy of holies to the Lord."
