And the LORD said unto Moses, Speak unto the priests the sons of Aaron, and say unto them, There shall none be defiled for the dead among his people:
But for his kin, that is near unto him, that is, for his mother, and for his father, and for his son, and for his daughter, and for his brother,
Neither shall he go in to any dead body, nor defile himself for his father, or for his mother;
