'Dead' in the Bible

And Naomi saith to her two daughters-in-law, 'Go, turn back, each to the house of her mother; Jehovah doth with you kindness as ye have done with the dead, and with me;

And Naomi saith to her daughter-in-law, 'Blessed is he of Jehovah who hath not forsaken His kindness with the living and with the dead;' and Naomi saith to her, 'The man is a relation of ours; he is of our redeemers.'

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 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.'
