Rather, When a man makes a special vow which concerns thy valuation of persons to Yahweh, if thy estimation shall be of the male, etc. The expression "thy estimation" is addressed either to Moses or to the priest Leviticus 27:12 : it denoted a legal valuation. The vow of a person was perhaps most frequently made in cases of illness or danger, under the impulse of religions feeling, either in the way of thankfulness for blessings received, or of supplication for something desired. A man might dedicate himself, his wife, his child, or his bondservant. This might have been an old custom; but the Law ordained that he who had taken such a vow should pay a sum of money to the sanctuary, determined according to the age and sex of the person.

When a man shall make a singular vow - The verse is short and obscure, and may be translated thus: A man who shall have separated a vow, according to thy estimation, of souls unto the Lord; which may be paraphrased thus: He who shall have vowed or consecrated a soul, i. e., a living creature, whether man or beast, if he wish to redeem what he has thus vowed or consecrated, he shall ransom or redeem it according to the priest's estimation; for the priest shall judge of the properties, qualifications, and age of the person or beast, and the circumstances of the person who has vowed it, and shall regulate the value accordingly; and the money shall be put into his hands for the service of the sanctuary. A vow (says Mr. Ainsworth) is a religious promise made unto the Lord, and for the most part with prayer, and paid with thanksgiving, Numbers 21:2, Numbers 21:3; Psalm 66:12, Psalm 66:14. Vows were either of abstinence, such as are spoken of Numbers 30, and the vow of the Nazarite, Numbers 6; or they were to give something to the Lord, as sacrifices, Leviticus 7:16, or the value of persons, beasts, houses, or lands, concerning which the law is here given. A man might vow or devote himself, his children, (Leviticus 27:5, Leviticus 27:6), his domestics, his cattle, his goods, etc. And in this chapter rules are laid down for the redemption of all these things. But if, after consecrating these things, he refused to redeem them, then they became the Lord's property for ever. The persons continued all their lives devoted to the service of the sanctuary; the goods were sold for the profit of the temple or the priests; the animals, if clean, were offered in sacrifice; if not proper for sacrifice, were sold, and the price devoted to sacred uses. This is a general view of the different laws relative to vows, mentioned in this chapter.

Speak unto the children of Israel, and say unto them, When a man shall make a (a) singular vow, the persons [shall be] for the LORD by (b) thy estimation.
(a) As of his son or daughter.
(b) Who art the priest.

Speak unto the children of Israel, and say unto them,.... This being an affair which only concerned them; for the Jewish writers say (h), by this phrase, the children of Israel, Gentiles are excluded:
when a man shall make a singular vow; an unusual, an uncommon one, a very distinguished one, and even what is wonderful, as the word signifies; as when a man, through uncommon zeal for God and his service, devotes himself, or his children, or his cattle, or his houses or fields, to the Lord: the word "man", the Jewish writers say (i), includes every male, and even a Gentile; yea, it is said all estimate and are estimated, vow and are vowed, priests, and Levites, and Israelites, women and servants (k): the persons shall be for the Lord by thy estimation: as when a man devoted himself or any that belonged to him to the service of the sanctuary, out of his great zeal for it, as to assist the priests and Levites in the meaner sort of work, as to carry wood and draw water, and sweep the tabernacle, and the like; they were not allowed to do these things, partly because it was not the will of God that any or every Israelite should be employed in such menial service, and partly because there were men appointed for such work, as well as to prevent too great a number of persons in the sanctuary, which would be troublesome, and only stand in one another's way; wherefore, on every devoted person to such service a value or price was set, according to the rules after given, which were to be paid in to the priests for the service of the sanctuary, the repair of the house, &c. see 2-Kings 12:4; the word may be rendered, agreeably to the accents, "according to thy estimation of souls (or persons) the vow shall be to the Lord" (l); that is, the price of the person devoted, according to the estimation of the priest, or as settled by the Lord in some following verses, shall be given to him: the word "souls" being used, the Jewish doctors understand it of estimation or value of that on which the soul or life depends; thus, for instance, if a man says, the value of my hand or of my feet be upon me, he says nothing; but if he says, the value of my head or of my liver be upon me, he gives the whole value, i.e. of himself; if he says, the half of my value be upon me, he gives the half of it; but if he says, the value of half of me, he gives the whole value: this is the general rule, that on which the soul or life depends pays the whole value (m); for a man cannot live without his head, or without his liver, or when half of himself is taken away.

CONCERNING VOWS. (Leviticus. 27:1-18)
When a man shall make a singular vow, &c.--Persons have, at all times and in all places, been accustomed to present votive offerings, either from gratitude for benefits received, or in the event of deliverance from apprehended evil. And Moses was empowered, by divine authority, to prescribe the conditions of this voluntary duty.
the persons shall be for the Lord, &c.--better rendered thus:--"According to thy estimation, the persons shall be for the Lord." Persons might consecrate themselves or their children to the divine service, in some inferior or servile kind of work about the sanctuary (1-Samuel 3:1). In the event of any change, the persons so devoted had the privilege in their power of redeeming themselves; and this chapter specifies the amount of the redemption money, which the priest had the discretionary power of reducing, as circumstances might seem to require. Those of mature age, between twenty and sixty, being capable of the greatest service, were rated highest; young people, from five till twenty, less, because not so serviceable; infants, though devotable by their parents before birth (1-Samuel 1:11), could not be offered nor redeemed till a month after birth; old people were valued below the young, but above children; and the poor--in no case freed from payment, in order to prevent the rash formation of vows--were rated according to their means.

The vowing of persons. - "If any one make a special vow, souls shall be to the Lord according to thy valuation." נדר הפליא does not mean to dedicate or set apart a vow, but to make a special vow (see at Leviticus 22:21). The words בּערכּך, "according to thy (Moses') valuation," it is more simple to regard as an apodosis, so as to supply to ליהוה the substantive verb תּהיינה, than as a fuller description of the protasis, in which case the apodosis would follow in Leviticus 27:3, and the verb יקדּישׁ would have to be supplied. But whatever may be the conclusion adopted, in any case this thought is expressed in the words, that souls, i.e., persons, were to be vowed to the Lord according to Moses' valuation, i.e., according to the price fixed by Moses. This implies clearly enough, that whenever a person was vowed, redemption was to follow according to the valuation. Otherwise what was the object of valuing them? Valuation supposes either redemption or purchase. But in the case of men (i.e., Israelites) there could be no purchasing as slaves, and therefore the object of the valuing could only have been for the purpose of redeeming, buying off the person vowed to the Lord, and the fulfilment of the vow could only have consisted in the payment into the sanctuary of the price fixed by the law.
(Note: Saalschtz adopts this explanation in common with the Mishnah. Oehler is wrong in citing 1-Samuel 2:11, 1-Samuel 2:22, 1-Samuel 2:28 as a proof of the opposite. For the dedication of Samuel did not consist of a simple vow, but was a dedication as a Nazarite for the whole of his life, and Samuel was thereby vowed to service at the sanctuary, whereas the law says nothing about attachment to the sanctuary in the case of the simple vowing of persons. But because redemption in the case of persons was not left to the pleasure or free-will of the person making the vow as in the case of material property, no addition is made to the valuation price as though for a merely possible circumstance.)

A singular vow - Or, an eminent, or hard vow, not concerning things, which was customary, but concerning persons, which he devoted to the Lord, which was unusual and difficult: yet there want not instances of persons who devoted either themselves or their children, and that either more strictly, 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, as some who were not Levites, might yet through zeal to God, or to obtain God's help, which they wanted or desired, devote themselves or their children to the service of God and of the sanctuary, tho' not in such a way as the Levites, which was forbidden, 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 to the sanctuary, an exchange is allowed, and the priests are directed to receive a tax for their redemption. By thy estimation - 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, Leviticus 27:12.
