Leviticus 25
39 Ref And 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;
40 Ref But let him be with you as a servant working for payment, till the year of Jubilee;
41 Ref Then 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.
42 Ref For they are my servants whom I took out from the land of Egypt; they may not become the property of another.
43 Ref Do not be a hard master to him, but have the fear of God before you.
