Matthew Henry on Leviticus 27:14-25
Here is the law concerning real estates dedicated to the service of God by a singular vow.
I. Suppose a man, in his zeal for the honour of God, should sanctify his house to God (Lev 27:14), the house must be valued by the priest, and the money got by the sale of it was to be converted to the use of the sanctuary, which by degrees came to be greatly enriched with dedicated things, Kg1 15:15. But, if the owner be inclined to redeem it himself, he must not have it so cheap as another, but must add a fifth part to the price, for he should have considered before he had vowed it, Lev 27:15.
