'Raise Up the Name of the Dead' in the Bible

And Boaz will say, In the day of thy buying the field from the hand of Naomi, and from Ruth the Moabitess, the wife of the dead, thou boughtest it to raise up the name of the dead upon his inheritance.

And also Ruth the Moabitess, the wife of Mahlon, I bought to me for a wife, to raise up the name of the dead upon his inheritance; and the name of the dead shall not be cut off from his brethren and from the gate of his place: ye are witnesses this day.
