“And if a sojourner or a stranger wax rich by thee, and thy brother that dwelleth by him wax poor, and sell himself unto the stranger or sojourner by thee, or to the stock of the stranger’s family; after that he is sold, he may be redeemed again; and one of his brethren may redeem him. Either his uncle or his uncle’s son may redeem him, or any that is nigh of kin unto his family may redeem him; or, if he be able, he may redeem himself: * * * and if he be not redeemed in one of these years,—then he shall go out in the year of Jubilee, both he and his children with him.” _Lev._ xxv. 47–54. “Now these are the judgments which ye shall set before them. If ye buy an Hebrew servant, six years shall he serve, and in the seventh he shall go out free for nothing. If he came in by himself, he shall go out by himself; if he were married, then his wife shall go out with him. If his master have given him a wife, and she have borne him sons or daughters, the wife and her children shall be her master’s, and he shall go out by himself; and if the servant shall plainly say, ‘I love my master, my wife, and my children; I will not go out free,’—then his master shall bring him unto the judges; he shall bring him unto the door, or unto the door-post, and his master shall bore his ear through with an awl, and he shall serve him for ever.” _Ex._ xxi. 1–6. It is clear, then, that “to contract and consent,” or the reverse, is no part of the qualities of slavery. Erase, then, that portion of Dr. Paley’s definition as surplusage; it will then read, “an obligation to labour for the benefit of the master.” Now, there can be no obligation to do a thing where there is no possible power to do it; and more especially, if there is no contract. But it does not unfrequently occur, that a slave, from its infancy, old age, idiocy, delirium, disease, or other infirmity, has no power to labour for the benefit of the master; and the want of such ability may be obviously as permanent as life, so as to exclude the idea of any prospective benefit. Yet the law compels the master to supply food, clothes, medicine, pay taxes on, and every way suitably protect such slave, greatly to the disadvantage of the master. Or, a case might be, for it is presumable, that the master, from some obliqueness of understanding, might not wish some slave, even in good health, to labour at all, but would prefer, at great expense, to maintain such slave in luxury and idleness, clothed in purple and fine linen, and faring sumptuously every day: surely, such slave, would be under no obligation to labour for the benefit of the master, when, to do so, would be acting contrary to his will and command. Yet none of these circumstances make the slave a freeman, or alter at all the essentials of slavery.
