Now this was the custom in former times in Israel concerning redeeming and exchanging: to confirm a transaction, the one took off a sandal and gave it to the other; this was the manner of attesting in Israel. So when the next-of-kin said to Boaz, “Acquire it for yourself,” he took off his sandal. Then Boaz said to the elders and all the people, “Today you are witnesses that I have acquired from the hand of Naomi all that belonged to Elimelech and all that belonged to Chilion and Mahlon. I have also acquired Ruth the Moabite, the wife of Mahlon, to be my wife, to maintain the dead man’s name on his inheritance, in order that the name of the dead may not be cut off from his kindred and from the gate of his native place; today you are witnesses.” (Ruth 4:7-10, NRSV)
So Boaz removed his shoe and purchased the land and legally acquired Ruth as his wife.
Since the unnamed relative was not able or unwilling to marry Ruth and carry on Elimelech/Mahlon’s name Boaz was able to marry Ruth and provide for her and Naomi.
Would we be so bold as to do this for a relative?
How much are we willing to give to help others live?
