Ruth:4:9: And Boaz said unto the elders, and unto all the people, Ye are witnesses this day, that I have bought all that was Elimelech's, and all that was Chilion's and Mahlon's, of the hand of Naomi.
Ruth:4:10: Moreover Ruth the Moabitess, the wife of Mahlon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day.

Here, Boaz declared that he had purchased Ruth along with all of his dead relative's possessions. As we have seen, again and again, women were treated like slaves or cattle throughout the Bible. Boaz at first had encouraged another relative to buy Ruth, but he refused, so Boaz bought her. What valuable moral lesson do we learn from this book of the Bible?
