'Dead' in the Bible

And I will lay the dead carcases of the children of Israel before their idols; and I will scatter your bones round about your altars.

Forbear to cry, make no mourning for the dead, bind the tire of thine head upon thee, and put on thy shoes upon thy feet, and cover not thy lips, and eat not the bread of men.

And they shall come at no dead person to defile themselves: but for father, or for mother, or for son, or for daughter, for brother, or for sister that hath had no husband, they may defile themselves.

The priests shall not eat of any thing that is dead of itself, or torn, whether it be fowl or beast.
