Deuteronomy 24:7-9

7“If a man is caught kidnapping any of his countrymen from the sons of Israel, and he treats him violently or sells him [as a slave], then that thief shall die. So you shall remove the evil from among you.

8“Be careful during an outbreak of leprosy, that you diligently observe and do according to all that the Levitical priests teach you; just as I have commanded them, so you shall be careful to do.

9Remember [with thoughtful concern] what the Lord your God did to Miriam on the road as you came out of Egypt.
