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: (Leviticus 21:1)
Ezekiel 44:25
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.
