"Both thy bond-men, and thy bond-maids, which thou shalt have, shall be of the heathen that are round about you; of them ye shall buy bond-men and bond-maids. Moreover, of the children of the strangers that do sojourn among you, of them shall ye buy and of their families that are with you, which they begat in your land; and they shall be your possession. And ye shall take them as an inheritance for your children after you, to inherit them for a possession, they shall be your bond-men forever." _Leviticus_ xxv. 44-47.
