| Gill's Exposition of the Entire Bible And as a yearly hired servant shall he be with him,.... Being redeemable every year, and upon his redemption might quit his master's service, as an hireling may; and the price of his redemption to be valued according to the years he served, and as if he had been hired for so much a year; as well as he was to be treated in a kind and gentle manner, not as a bondman, but as if he was an hired servant, as follows: and the other shall not rule with rigour over him in thy sight; the person he is sold unto, his master, a sojourner or stranger, he might not use an Hebrew he had bought with any severity; for if an Hebrew master might not use an Hebrew servant with rigour, it was not by any means to be admitted in the commonwealth of Israel for a proselyte to use one in such a manner, and that openly, in the sight of an Israelite his neighbour; he looking on and not remonstrating against it, or acquainting the civil magistrate with it, who had it in his power to redress such a grievance, and ought to do it.
Keil and Delitzsch Biblical Commentary on the Old TestamentDuring the time of service the buyer was to keep him as a day-labourer year by year, i.e., as a labourer engaged for a term of years, and not rule over him with severe oppression. "In thine eyes," i.e., so that thou (the nation addressed) seest it.
Geneva Study BibleAnd as a yearly hired servant shall he be with him: and the other shall not rule with rigour over him in thy {y} sight. (y) You shall not allow him to treat him severely, if you know it.
Wesley's Notes 25:53 In thy sight - Thou shalt not suffer this to be done, but whethe thou art a magistrate, or a private person, thou shalt take care according to thy capacity to get it remedied.
Matthew Henry's Concise Commentary25:39-55 A native Israelite, if sold for debt, or for a crime, was to serve but six years, and to go out the seventh. If he sold himself, through poverty, both his work and his usage must be such as were fitting for a son of Abraham. Masters are required to give to their servants that which is just and equal, Col 4:1. At the year of jubilee the servant should go out free, he and his children, and should return to his own family. This typified redemption from the service of sin and Satan, by the grace of God in Christ, whose truth makes us free, Joh 8:32. We cannot ransom our fellow-sinners, but we may point out Christ to them; while by his grace our lives may adorn his gospel, express our love, show our gratitude, and glorify his holy name. |
