'Dead' in the Bible

Naomi said to her two daughters-in-law, "Go, return each of you to her mother's house: Yahweh deal kindly with you, as you have dealt with the dead, and with me.

Naomi said to her daughter-in-law, "Blessed be he of Yahweh, who has not left off his kindness to the living and to the dead." Naomi said to her, "The man is a close relative to us, one of our near kinsmen."

Then Boaz said, "On the day you buy the field from the hand of Naomi, you must buy it also from Ruth the Moabitess, the wife of the dead, to raise up the name of the dead on his inheritance."

Moreover Ruth the Moabitess, the wife of Mahlon, I have purchased to be my wife, to raise up the name of the dead on his inheritance, that the name of the dead not be cut off from among his brothers, and from the gate of his place. You are witnesses this day."
