Leviticus 25:44-51

⁴⁴And as for thy bondman and thy handmaid whom thou shalt have — of the nations that are round about you, of them shall ye buy bondmen and handmaids.

⁴⁵Moreover of the children of them that dwell as sojourners with you, of them may ye buy, and of their family that is with you, which they beget in your land, and they shall be your possession.

⁴⁶And ye shall leave them as an inheritance to your children after you, to inherit them as a possession: these may ye make your bondmen for ever; but as for your brethren, the children of Israel, ye shall not rule over one another with rigour.

⁴⁷And if a stranger or sojourner become wealthy beside thee, and thy brother beside him grow poor, and sell himself unto the stranger, who is settled by thee, or to a scion of the stranger's family,

⁴⁸after that he is sold there shall be right of redemption for him; one of his brethren may redeem him.

⁴⁹Either his uncle or his uncle's son may redeem him, or one of his next relations of his family may redeem him; or if his means be sufficient, he may redeem himself.

⁵⁰And he shall reckon with him that bought him from the year that he was sold to him unto the year of jubilee; and the price of his sale shall be according to the number of the years, according to the days of a hired servant shall he be with him.

⁵¹If there are yet many years, according unto them shall he return his redemption money out of the money that he was bought for;
