Leviticus 27:2

A singular vow, or, an eminent or hard or wonderful vow; not concerning things, which was not strange, but customary; but concerning persons, as it here follows, which he vowed, or by vow devoted unto the Lord, which indeed was unusual and difficult: yet there want not instances of such vows, and of persons which devoted either themselves or their children to the service of God, and that either more strictly and particularly, as the Nazarites and the Levites, 1 Samuel 1:11, and for these there was no redemption admitted, but they were in person to perform the service to which they were devoted; or more largely and generally, as some who were not Levites, nor intended themselves or their children should be Nazarites, might yet, through zeal to God and his service, or to obtain God's help in giving them some mercy which they wanted and desired, or in freeing them from some evil felt or feared, devoted themselves or their children to the service of God and of the sanctuary, though not in such a way as the Levites, which they were forbidden to do, yet in some kind of subserviency to them. And because there might be too great a number of persons thus dedicated, which might be burdensome and chargeable to the sanctuary, therefore an exchange is allowed, and the priests are directed to impose and require a tax for their redemption. For the Lord, i.e. dedicated to the Lord, and consequently to the priest. By whose estimation? Answ. Either,

1. Thine, O priest, to whom the valuation of things belonged, and here is ascribed, Leviticus 27:12. Or rather,

2. Thine, O man that vowest, as appears from Leviticus 27:8, where his estimation is opposed to the priest's valuation. Nor was there any fear of his partiality in his own cause, for the price is particularly limited. But where the price is undetermined, there, to avoid that inconvenience, the priest is to value it, as Leviticus 27:8,12.
