Boaz's declaration to marry Ruth is a pivotal moment in the story, reflecting the cultural and legal practices of ancient Israel. In those times, it was customary for a close relative to marry a widow to preserve the deceased husband's family line and property. This practice, known as levirate marriage, ensured that the family name and inheritance were not lost. Boaz, a man of integrity and compassion, steps up to fulfill this role for Ruth, who is a foreigner and a widow, showing great kindness and respect for her and her late husband Mahlon.
By taking Ruth as his wife, Boaz not only honors the memory of Mahlon but also provides Ruth with security and a place within the community. This act of redemption is a testament to Boaz's character and the values of loyalty and responsibility. It underscores the importance of community support and the willingness to uphold familial duties. The witnesses mentioned in the verse serve to legitimize the transaction and ensure that the community acknowledges and supports this union. Boaz's actions ultimately lead to the continuation of a family line that would become significant in the lineage of King David and, according to Christian tradition, Jesus Christ.
