(2) Shall make a singular vow.--Better, shall consecrate a vow. (See Leviticus 22:21.) According to the interpretation of this phrase which obtained during the second Temple it denotes shall pronounce a vow. Hence the ancient Chaldee Versions render it, "shall distinctly pronounce a vow." Accordingly, no vow mentally made or conceived was deemed binding. It had to be distinctly pronounced in words. The form of the vow is nowhere given in the Bible. Like many other points of detail, the wording of it was left to the administrators of the law. They divided vows into two classes: (1) Positive vows, by which a man bound himself to consecrate for religious purposes his own person, those members of his family over whom he had control, or any portion of his property, and for this kind of vow the formula was "Behold I consecrate this to the Lord"; and (2) Negative vows, by which he promised to abstain from enjoying a certain thing, for which the formula was, "Such and such a thing be unlawful to me for so many days, weeks, or for ever."

The persons shall be for the Lord by thy estimation.--Better, souls to the Lord according to thy estimation., that is, the vow consists of consecrating persons to the Lord with the intention of redeeming by money the persons thus consecrated, according to the valuation put upon them by Moses. This part of the verse explains the nature of the vow, and takes it for granted that by consecrating a human being to God by a vow is meant to substitute the money value for him. By the suffix, "thy estimation," Moses is meant, to whom these regulations are here Divinely communicated, and upon whom it devolved in the first instance to carry out the law. (See Leviticus 5:15; Leviticus 5:18.) During the second Temple any Israelite could estimate the money value of a person thus vowed to the Lord.

Verse 2. - When a man shall make a singular vow, - literally, when a man shall separate a vow, that is, make a special vow (see Numbers 6:2) - the persons shall be for the Lord by thy estimation; that is, when a man has vowed himself or another person to the Lord, the priest shall declare the amount at which the person vowed is to be redeemed.

27:1-13 Zeal for the service of God disposed the Israelites, on some occasions, to dedicate themselves or their children to the service of the Lord, in his house for life. Some persons who thus dedicated themselves might be employed as assistants; in general they were to be redeemed for a value. It is good to be zealously affected and liberally disposed for the Lord's service; but the matter should be well weighed, and prudence should direct as to what we do; else rash vows and hesitation in doing them will dishonour God, and trouble our own minds.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.
