'Dead' in the Bible

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

or a charmer, or one that inquireth of a spirit of Python, or a soothsayer, or one that consulteth the dead.

If brethren dwell together, and one of them die, and have no son, the wife of the dead shall not marry a stranger abroad: her husband's brother shall go in unto her, and take her to him as wife, and perform the duty of a husband's brother unto her.

And it shall be, that the firstborn that she beareth shall stand in the name of his brother who is dead, that his name be not blotted out from Israel.

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