An OT term meaning a relative who volunteered to take responsibility for the extended family. Boaz fulfilled this responsibility for the widow Ruth, undertaking to care for her and ultimately marrying her (Ruth 2:5-4:15). Boaz is one of the ‘types’ or biblical pictures in Scripture. We have a kinsman/redeemer in Jesus who stepped into our predicament by coming to earth and dying on the cross. He redeemed us from our hopeless situation and we have become a part of His bride (the church) and His possession (1 Pet 1:18,19; Rev 19:9, 21:9).
