Jezekiel 44:26

26 And after he has been cleansed, let him number to himself seven days.

Jezekiel 44:26 In-Context

24 And these shall attend at a judgment of blood to decide it: they shall rightly observe my ordinances, and judge my judgments, and keep my statutes and my commandments in all my feasts; and they shall hallow my sabbaths.
25 And they shall not go in to the dead body of a man to defile themselves: only may defile himself for a father, or for a mother, or for a son, or for a daughter, or for a brother, or for his sister, who has not been married.
26 And after he has been cleansed, let him number to himself seven days.
27 And on whatsoever day they shall enter into the inner court to minister in the holy place, they shall bring a propitiation, saith the Lord God.
28 And it shall be to them for an inheritance: I am their inheritance: and no possession shall be given them among the children of Israel; for I am their possession.
