23And they shall teach my people the difference between the holy and profane, and cause them to discern between the unclean and the clean. 24And in controversy they shall stand in judgment; and they shall judge it according to my judgments: and they shall keep my laws and my statutes in all mine assemblies; and they shall hallow my sabbaths. 25And 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. 26And after he is cleansed, they shall reckon unto him seven days.27And 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. 28And it shall be unto them for an inheritance: I am their inheritance: and ye shall give them no possession in Israel: I am their possession. 29They shall eat the meat offering, and the sin offering, and the trespass offering; and every dedicated thing in Israel shall be theirs.
