Ruth 2:20

20“The LORD bless him!” Naomi said to her daughter-in-law. “He has not stopped showing his kindness to the living and the dead.” She added, “That man is our close relative; he is one of our guardian-redeemers. The Hebrew word for guardian-redeemer is a legal term for one who has the obligation to redeem a relative in serious difficulty (see Lev. 25:25-55). ”
