Deuteronomy 24:9

Ver. 9. Remember what the Lord thy God did unto Miriam— This may be understood, either as an admonition, that they ought not to think much of being shut out of the camp, and going through the appointed purifications for the leprosy, since a person of so much distinction as Miriam was not exempted from that law; or it may be considered as an exhortation, to take care lest they spoke evil of dignities, or disobeyed the command of the priest, which might bring such a stroke upon them as God inflicted upon Miriam.
