Ezekiel 44:25-27

King James Version

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.

²⁶ And after he is cleansed, they shall reckon unto him seven days.

²⁷ And in the day that he goeth into the sanctuary, unto the inner court, to minister in the sanctuary, he shall offer his sin offering, saith the Lord God.
