Leviticus 25:47-55

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.

⁵¹If there is still a long time, he will give back, on account of it, a part of the price which was given for him.

⁵²And if there is only a short time, he will take account of it with his master, and in relation to the number of years he will give back the price of making him free.

⁵³And he will be with him as a servant working for payment year by year; his master is not to be cruel to him before your eyes.

⁵⁴And if he is not made free in this way, he will go out in the year of Jubilee, he and his children with him.

⁵⁵For the children of Israel are servants to me; they are my servants whom I took out of the land of Egypt: I am the Lord your God.
