If he be poorer than thy estimation - Too poor (to pay) thy valuation. Compare Leviticus 27:7, Leviticus 27:11.

But if he be poorer than thy estimation,.... If he is so poor that he is not able to pay the value that, is set upon him, according to the rules before given:

then he shall present himself before the priest; that has made the estimation, according to the above directions, observing the difference of years, and of male and female; but if a person could not pay the said sums that were appointed, he might apply to the priest, and tell his case:

and the priest shall value him; put a price upon him he is able to pay, as follows:

according to his ability that vowed shall the priest value him; he was to examine into his circumstances, and as they appeared to him he was to put a value on him, which was to be paid, but not less than, a shekel; for if he could not pay that, it was to remain as a debt until he could (q); and it was the ability of him that made the vow that was to be inquired into, and according to which the estimation was to be made, and not of him that was vowed: so it is said in the Misnah,"ability is regarded in the vower, and years in the vowed, and estimations in the estimated, and according to the tithe of the estimation: ability in the vower, how? a poor man that estimates a rich man, pays the value of a poor man; and a rich man that estimates a poor man, pays the value of a rich man: if he is poor and afterwards becomes rich, or rich and afterwards poor, he pays the price of a rich man (r);''but the sense which Jarchi gives is, that a priest in such a case was to judge according to what a man has, and so order him to pay, but was to leave him so as he might live, a bed and bolster, and working tools, and if he had an ass he might leave him that.

(q) Maimon. Hilchot Eracin, c. 3. sect. 4. (r) Misn. Eracin, c. 4. sect. 1, 2.

But if the person making the vow was "poor before thy valuation," i.e., too poor to be able to pay the valuation price fixed by the law, he was to be brought before the priest, who would value him according to the measure of what his hand could raise (see Leviticus 5:11), i.e., what he was able to pay. This regulation, which made it possible for the poor man to vow his own person to the Lord, presupposed that the person vowed would have to be redeemed. For otherwise a person of this kind would only need to dedicate himself to the sanctuary, with all his power for work, to fulfil his vow completely.

But if he be poorer {e} than thy estimation, then he shall present himself before the priest, and the priest shall value him; according to his ability that vowed shall the priest value him.

(e) If he is not able to pay according to your estimate.

27:8 Than thy estimation - If he be not able to pay the price which thou, according to the rules here given, requirest of him.

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.
