'Dead' in the Bible

Command the children of Israel, that they put out of the camp every leper, and every one that hath an issue, and whosoever is defiled by a dead person:

All the days that he hath consecrated himself to Jehovah, he shall come near no dead body.

And the priest shall offer one for a sin-offering, and the other for a burnt-offering, and make an atonement for him, for that he sinned by the dead person; and he shall hallow his head that same day.

He that toucheth a dead person, any dead body of a man, shall be unclean seven days.

Whoever toucheth a dead person, the dead body of a man that is dead, and purifieth not himself, defileth the tabernacle of Jehovah; and that soul shall be cut off from Israel; for the water of separation was not sprinkled upon him: he shall be unclean; his uncleanness is yet upon him.

And every one that toucheth one that is slain with a sword in the open fields, or a dead person, or the bone of a man, or a grave, shall be unclean seven days.

and a clean man shall take hyssop, and dip it in the water, and sprinkle it on the tent, and upon all the utensils, and upon the persons that were there, and upon him that hath touched the bone, or the one slain, or the dead person, or the grave;

And the whole assembly saw that Aaron was dead, and they mourned for Aaron thirty days, even the whole house of Israel.
