'Bought' in the Bible

And Boaz saith, 'In the day of thy buying the field from the hand of Naomi, then from Ruth the Moabitess, wife of the dead, thou hast bought it, to raise up the name of the dead over his inheritance.'

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.

and also Ruth the Moabitess, wife of Mahlon, I have bought to myself for a wife, to raise up the name of the dead over his inheritance; and the name of the dead is not cut off from among his brethren, and from the gate of his place; witnesses ye are to-day.'
