'Deceased' in the Bible

Then Boaz said, “On the day you buy the field from the hand of Naomi, you must also acquire Ruth the Moabitess, the widow of the deceased, in order to raise up the name of the deceased on his inheritance.”

Moreover, I have acquired Ruth the Moabitess, the widow of Mahlon, to be my wife in order to raise up the name of the deceased on his inheritance, so that the name of the deceased will not be cut off from his brothers or from the court of his birth place; you are witnesses today.”
