Then Boaz said, “When ¹  you acquire the field ²  from Naomi, ³  you must also ⁴  acquire Ruth the Moabite, ⁵  the wife of our deceased relative, ⁶  in order to preserve his family name by raising up a descendant who will inherit his property.” ⁷ 

(Now this used to be the customary way to finalize a transaction involving redemption in Israel: ¹  A man would remove his sandal and give it to the other party. ²  This was a legally binding act ³  in Israel.)

I have also acquired Ruth the Moabite, the wife of Mahlon, as my wife to raise up a descendant who will inherit his property ¹  so the name of the deceased might not disappear ²  from among his relatives and from his village. ³  You are witnesses today.”
