"'If thy brother that dwelleth by thee wax poor and sell himself unto thee, thou shalt not let him labour as a bondservant doeth:

"'If thou wilt have bondservants and maidens, thou shalt buy them of the heathen that are round about you,

They promise them liberty, and are themselves the bondservants of corruption. For of whomsoever a man is overcome, unto the same is he in bondage.
