[23] And they shall teach my people the difference between the holy and profane, and cause them to discern between the unclean and the clean. [24] And in controversy they shall stand in judgment; it according to my judgments: and they shall keep my laws and my statutes in all mine assemblies; and they shall hallow my sabbaths. [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 [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.
