The Kinsman-Redeemer
The classic illustration of redemption is found in the Book of Ruth. The framework of this touching idyll consists of two clauses of ancient Hebrew legislation: the law of Levirate marriage, rendering compulsory the widow’s marriage to her late husband’s next of kin, Deut 25:5-10, and the law of the kinsman redeemer, Lev 25:25-34. Adied by these two enactments, Ruth, the loyal but poverty-stricken stranger, was able to marry into the best family in the district and to become the ancestress of King David and of the Messiah.
By the kinsman-redeemer enactment, if a Hebrew falls into slavery and is forced to sell himself, his family, his estate, all that he sold can be compulsorily redeemed by the next of kin.
It will be noted that the kinsman-redeemer has three qualifications, and both Boaz and Christ had all of them.
