'Dead' in the Bible

So it came to pass, when all the men of war were consumed and dead from among the people,

Ye are the children of Jehovah your God: ye shall not cut yourselves, nor make any baldness between your eyes for the dead.

If brethren dwell together, and one of them die, and have no son, the wife of the dead shall not be married without unto a stranger: her husband's brother shall go in unto her, and take her to him to wife, and perform the duty of a husband's brother unto her.

And it shall be, that the first-born that she beareth shall succeed in the name of his brother that is dead, that his name be not blotted out of Israel.

I have not eaten thereof in my mourning, neither have I put away thereof, being unclean, nor given thereof for the dead: I have hearkened to the voice of Jehovah my God; I have done according to all that thou hast commanded me.

And thy dead body shall be food unto all birds of the heavens, and unto the beasts of the earth; and there shall be none to frighten them away.
