And when a man shall sanctify his house to be holy unto the LORD, then the priest shall estimate it, whether it be good or bad: as the priest shall estimate it, so shall it stand.

Wesley's Notes

27:14 Sanctify his house - By a vow, for of that way and manner of sanctification he speaks in this whole chapter .

Jamieson-Fausset-Brown Bible Commentary

14, 15. when a man shall sanctify his house to be holy unto the Lord, &c.-In this case, the house having been valued by the priest and sold, the proceeds of the sale were to be dedicated to the sanctuary. But if the owner wished, on second thought, to redeem it, he might have it by adding a fifth part to the price.

Matthew Henry's Concise Commentary

27:14-25 Our houses, lands, cattle, and all our substance, must be used to the glory of God. It is acceptable to him that a portion be given to support his worship, and to promote his cause. But God would not approve such a degree of zeal as ruined a man's family.

Matthew Henry's Whole Bible Commentary

Verses 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 (v. 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, 1 Ki. 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, v. 15. To him that was necessitous God would abate the estimation (v. 8); but to him that was fickle and humoursome, and whose second thoughts inclined more to the world and his secular interest than his first, God would rise in the price. Blessed be God, there is a way of sanctifying our houses to be holy unto the Lord, without either selling them or buying them. If we and our houses serve the Lord, if religion rule in them, and we put away iniquity far from them, and have a church in our house, holiness to the Lord is written upon it, it is his, and he will dwell with us in it.

II. Suppose a man should sanctify some part of his land to the Lord, giving it to pious uses, then a difference must be made between land that came to the donor by descent and that which came by purchase, and accordingly the case altered.

1. If it was the inheritance of his fathers, here called the field of his possession, which pertained to his family from the first division of Canaan, he might not give it all, no, not to the sanctuary; God would not admit such a degree of zeal as ruined a man's family. But he might sanctify or dedicate only some part of it, v. 16. And in that case, (1.) The land was to be valued (as our countrymen commonly compute land) by so many measures' sowing of barley. So much land as would take a homer, or chomer, of barley, which contained ten ephahs, Eze. 45:11 (not, as some have here mistaken it, an omer, which was but a tenth part of an ephah, Ex. 16:36), was valued at fifty shekels, a moderate price (v. 16), and that if it were sanctified immediately from the year of jubilee, v. 17. But, if some years after, there was to be a discount accordingly, even of that price, v. 18. And, (2.) When the value was fixed, the donor might, if he pleased, redeem it for sixty shekels the homer's sowing, which was with the addition of a fifth part: the money then went to the sanctuary, and the land reverted to him that had sanctified it, v. 19. But if he would not redeem it, and the priest sold it to another, then at the year of jubilee, beyond which the sale could not go, the land came to the priests, and was theirs for ever, v. 20, 21. Note, What is given to the Lord ought not to be given with a power of revocation; what is devoted to the Lord must be his for ever, by a perpetual covenant.

2. If the land was his own purchase, and came not to him from his ancestors, then not the land itself, but the value of it was to be given to the priests for pious uses, v. 22, 24. It was supposed that those who, by the blessing of God, had grown so rich as to become purchasers would think themselves obliged in gratitude to sanctify some part of their purchase, at least (and here they are not limited, but they might, if they pleased, sanctify the whole), to the service of God. For we ought to give as God prospers us, 1 Co. 16:2. Purchasers are in a special manner bound to be charitable. Now, forasmuch as purchased lands were by a former law to return at the year of jubilee to the family from which they were purchased, God would not have that law and the intentions of it defeated by making the lands corban, a gift, Mk. 7:11. But it was to be computed how much the land was worth for so many years as were from the vow to the jubilee; for only so long it was his own, and God hates robbery for burnt-offerings. We can never acceptably serve God with that of which we have wronged our neighbour. And so much money he was to give for the present, and keep the land in his own hands till the year of jubilee, when it was to return free of all encumbrances, even that of its being dedicated to him of whom it was bought. The value of the shekel by which all these estimations were to be made is here ascertained (v. 25); it shall be twenty gerahs, and every gerah was sixteen barley-corns. This was fixed before (Ex. 30:13); and, whereas there had been some alterations, it is again fixed in the laws of Ezekiel's visionary temple (Eze. 45:12), to denote that the gospel should reduce things to their ancient standard.
