Exodus 21:2

If thou buy an Hebrew servant. — Ancient society was founded upon slavery. “The ultimate elements of the household,” says Aristotle, “are the master and his slave, the husband and his wife, the father and his children” (Pol. i. 2, § 1). In any consideration of the rights of persons, those of the slave class naturally presented themselves first of all, since they were the most liable to infraction. Slaves might be either natives or foreigners. A Hebrew could become a slave — (1) through crime (Exodus 22:3); (2) through indebtedness (Leviticus 25:39); (3) through his father’s right to sell him (Nehemiah 5:5). Foreign slaves might be either prisoners taken in war, or persons bought of their owners (Leviticus 25:45). The rights of Hebrew slaves are here specially considered.

Six years shall he serve. — The Hebrew was not to be retained in slavery for a longer space than six years. If a jubilee year occurred before the end of the six years, then he regained his freedom earlier (Leviticus 25:39); but in no case could he be retained more than six years in the slave condition, except by his own consent, formally given (Exodus 21:5). This law was an enormous advance upon anything previously known in the slave legislation of the most civilised country, and stamps the Mosaic code at once as sympathising with the slave, and bent on ameliorating his lot. It has been thought strange by some that slavery was not now abrogated; but even Christianity, fifteen hundred years later, did not venture on so complete a social revolution.
