Ever read the book of Ruth and wonder what the kinsman redeemer was? Or wander why Boaz married Ruth? A kinsman redeemer, redeemed a family and its property if the widow lost her husband and had no sons to pass on the family name. I plan on answering those questions in detail as well as provide a real life example from the book of Ruth. The Bible describes the responsibilities of a kinsman redeemer in the book of Deuteronomy. The widow of a family without an heir was not to marry an outsider.
