8 “When there is an outbreak of leprosy,* be very careful to do according to all that the Levitical priests will instruct you.+ Be careful to do exactly as I commanded them.

23 “‘They should instruct my people about the difference between what is holy and what is common; and they will teach them the difference between what is unclean and what is clean.+

7 For the lips of a priest should safeguard knowledge, and people should seek the law* from his mouth,+ because he is the messenger of Jehovah of armies.

14 When he saw them, he said to them: “Go and show yourselves to the priests.”+ Then as they were going off, they were cleansed.+
