The Lord said to Moses: “Say to the priests, the sons of Aaron – say to them, ‘For a dead person ¹  no priest ²  is to defile himself among his people, ³ 

Say to them, ‘Throughout your generations, ¹  if any man from all your descendants approaches the holy offerings which the Israelites consecrate ²  to the Lord while he is impure, ³  that person must be cut off from before me. ⁴  I am the Lord.
