This is part of the law concerning singular vows, extraordinary ones, which though God did not expressly insist on, yet, if they were consistent with and conformable to the general precepts, he would be well pleased with. Note, We should not only ask, What must we do, but, What may we do, for the glory and honour of God? As the liberal devises liberal things (Isa 32:8), so the pious devises pious things, and the enlarged heart would willingly do something extraordinary in the service of so good a Master as God is. When we receive or expect some singular mercy it is good to honour God with some singular vow.

I.The case is here put of persons vowed to God by a singular vow, Lev 27:2. If a man consecrated himself, or a child, to the service of the tabernacle, to be employed there in some inferior office, as sweeping the floor, carrying out ashes, running of errands, or the like, the person so consecrated shall be for the Lord, that is, "God will graciously accept the good-will." Thou didst well that it was in thy heart, Ch2 6:8. But forasmuch as he had no occasion to use their service about the tabernacle, a whole tribe being appropriated to the use of it, those that were thus vowed were to be redeemed, and the money paid for their redemption was employed for the repair of the sanctuary, or other uses of it, as appears by Kg2 12:14, where it is called, in the margin, the money of the souls of his estimation. A book of rates is accordingly provided, by which the priests were to go in their estimation. Here is, 1. The rate of the middle-aged, between twenty and threescore, these were valued highest, because most serviceable; a male fifty shekels, and a female thirty, Lev 27:3, Lev 27:4. The females were then less esteemed, but not so in Christ; for in Christ Jesus there is neither male nor female, Gal 3:28. Note, Those that are in the prime of their time must look upon themselves as obliged to do more in the service of God and their generation than can be expected either from minors, that have not yet arrived to their usefulness, or from the aged, that have survived it. 2. The rate of the youth between five years old and twenty was less, because they were then less capable of doing service, Lev 27:5. 3. Infants under five years old were capable of being vowed to God by their parents, even before they were born, as Samuel was, but not to be presented and redeemed till a month old, that, as one sabbath passed over them before they were circumcised, so one new moon might pass over them before they were estimated; and their valuation was but small, Lev 27:6. Samuel, who was thus vowed to God, was not redeemed, because he was a Levite, and a particular favourite, and therefore was employed in his childhood in the service of the tabernacle. 4. The aged are valued less than youth, but more than children, Lev 27:7. And the Hebrews observe that the rate of an aged woman is two parts of three to that of an aged man, so that in that age the female came nearest to the value of the male, which occasioned (as bishop Patrick quotes it here) this saying among them, That an old woman in a house is a treasure in a house. Paul sets a great value upon the aged women, when he makes them teachers of good things, Tit 2:3. 5. The poor shall be valued according to their ability, Lev 27:8. Something they must pay, that they might learn not to be rash in vowing to God, for he hath no pleasure in fools, Ecc 5:4. Yet not more than their ability, but secundum tenementum - according to their possessions, that they might not ruin themselves and their families by their zeal. Note, God expects and requires from men according to what they have, and not according to what they have not, Luk 21:4.

II.The case is put of beasts vowed to God, 1. If it was a clean beast, such as was offered in sacrifice, it must not be redeemed, nor any equivalent given for it: It shall be holy, Lev 27:9, Lev 27:10. After it was vowed, it was not to be put to any common use, nor changed upon second thoughts; but it must be either offered upon the altar, or, if through any blemish it was not meet to be offered, he that vowed it should not take advantage of that, but the priests should have it for their own use (for they were God's receivers), or it should be sold for the service of the sanctuary. This teaches caution in making vows and constancy in keeping them when they are made; for it is a snare to a man to devour that which is holy, and after vows to make enquiry, Pro 20:25. And to this that rule of charity seems to allude (Co2 9:7), Every man, according as he purposeth in his heart, so let him give. 2. If it was an unclean beast, it should go to the use of the priest at such a value; but he that vowed it, upon paying that value in money, and adding a fifth part more to it, might redeem it if he pleased, Lev 27:11-13. It was fit that men should smart for their inconstancy. God has let us know his mind concerning his service, and he is not pleased if we do not know our own. God expects that those that deal with him should be at a point, and way what they will stand to.

He shall not alter it, nor change it, a good for a bad, etc. - Whatever was consecrated to God by a vow, or purpose of heart, was considered from that moment as the Lord's property; to change which was impiety; to withhold it, sacrilege. Reader, hast thou ever dedicated thyself, or any part of thy property, to the service of thy Maker? If so, hast thou paid thy vows? Or hast thou altered thy purpose, or changed thy offering? Has he received from thy hands a bad for a good? Wast thou not vowed and consecrated to God in thy baptism? Are his vows still upon thee? Hast thou "renounced the devil and all his works, the pomps and vanities of this wicked world, and all the sinful lusts of the flesh?" Dost thou feel thyself bound "to keep God's holy will and commandments, and walk in the same all the days of thy life?" Was not this thy baptismal covenant? And hast thou renounced It? Take heed! God is not mocked: that which thou sowest, thou shalt also reap. If thou rob God of thy heart, he will deprive thee of his heaven.

And if it be any unclean beast, of which they do not offer a sacrifice unto the Lord,.... Any creature, excepting a dog, the price of which was not to be brought into the house of the Lord; besides oxen, sheep, goats, rams, and lambs; though some understand it even of such that have blemishes on them, and so not fit to be offered unto the Lord; so Jarchi and others (x):

then he shall present the beast before the priest; to be viewed, examined, and judged of as to its worth, and a value put upon it, that it might be sold or redeemed, as no other but a beast might; so it is observed birds, wood, frankincense, and ministering vessels, have no redemption, for it is only said a beast (y).

(x) Maimon. & Bartenora in Misn. Menachot, c. 12. sect. 1. (y) Misn. ib.

if it be a beast, whereof men bring an offering unto the Lord--a clean beast. After it had been vowed, it could neither be employed in common purposes nor exchanged for an equivalent--it must be sacrificed--or if, through some discovered blemish, it was unsuitable for the altar, it might be sold, and the money applied for the sacred service. If an unclean beast--such as an ass or camel, for instance, had been vowed, it was to be appropriated to the use of the priest at the estimated value, or it might be redeemed by the person vowing on payment of that value, and the additional fine of a fifth more.
