Ezekiel 44:25-27

Young's Literal Translation

²⁵ And unto any dead man they come not for uncleanness, but for father, and for mother, and for son, and for daughter, for brother, for sister who hath not been to a man, they defile themselves.

²⁶ `And after his cleansing, seven days they number to him.

²⁷ And in the day of his coming in unto the sanctuary, unto the inner court, to minister in the sanctuary, he bringeth near his sin-offering -- an affirmation of the Lord Jehovah.
