Leviticus 25:39-50

³⁹And if your brother becomes poor and gives himself to you for money, do not make use of him like a servant who is your property;

⁴⁰But let him be with you as a servant working for payment, till the year of Jubilee;

⁴¹Then he will go out from you, he and his children with him, and go back to his family and to the property of his fathers.

⁴²For they are my servants whom I took out from the land of Egypt; they may not become the property of another.

⁴³Do not be a hard master to him, but have the fear of God before you.

⁴⁴But you may get servants as property from among the nations round about; from them you may take men-servants and women-servants.

⁴⁵And in addition, you may get, for money, servants from among the children of other nations who are living with you, and from their families which have come to birth in your land; and these will be your property.

⁴⁶And they will be your children's heritage after you, to keep as their property; they will be your servants for ever; but you may not be hard masters to your countrymen, the children of Israel.

⁴⁷And if one from another nation living among you gets wealth, and your countryman, at his side, becomes poor and gives himself for money to the man from another nation or to one of his family;

⁴⁸After he has given himself he has the right to be made free, for a price, by one of his brothers,

⁴⁹Or his father's brother, or the son of his father's brother, or any near relation; or if he gets money, he may make himself free.

⁵⁰And let the years be numbered from the time when he gave himself to his owner till the year of Jubilee, and the price given for him will be in relation to the number of years, on the scale of the payment of a servant.
