Boaz has obtained the right to redeem Naomi’s property and to take Ruth as a wife, formally sealing the deal with an interesting sign and in front of the elders of the city.
Ruth 4:7 (NET) (Now this used to be the customary way to finalize a transaction involving redemption in Israel: A man would remove his sandal and give it to the other party. This was a legally binding act in Israel.) 8 So the guardian said to Boaz, “You may acquire it,” and he removed his sandal. 9 Then Boaz said to the leaders and all the people, “You are witnesses today that I have acquired from Naomi all that belonged to Elimelech, Kilion, and Mahlon. 10 I have also acquired Ruth the Moabite, the wife of Mahlon, as my wife to raise up a descendant who will inherit his property so the name of the deceased might not disappear from among his relatives and from his village. You are witnesses today.”
Deuteronomy 25:8 (NET) I donʼt want to marry her,” 9 then his sister-in-law must approach him in view of the elders, remove his sandal from his foot, and spit in his face. She will then respond, “Thus may it be done to any man who does not maintain his brotherʼs family line!” 10 His family name will be referred to in Israel as “the family of the one whose sandal was removed.”
