'Slave' in the Bible

"'When a man has sexual intercourse with a woman, although she is a slave woman designated for another man and she has not yet been ransomed, or freedom has not been granted to her, there will be an obligation to pay compensation. They must not be put to death, because she was not free.

"'If your brother becomes impoverished with regard to you so that he sells himself to you, you must not subject him to slave service.

Since they are my servants whom I brought out from the land of Egypt, they must not be sold in a slave sale.
