Deuteronomy 24:7-9

7“1If someone is 2caught kidnapping any of his countrymen of the sons of Israel, and he treats him as merchandise and sells him, then that thief shall die; so you shall eliminate the evil from among you.

8“3Be careful about an infestation of leprosy, that you are very attentive and act in accordance with everything that the Levitical priests teach you; just as I have commanded them, you shall be careful to act. 9Remember what the Lord your God did 4to Miriam on the way as you came out of Egypt.
