Jesus cleanses a man described with lepra/tzaraat-language and then commands him to show himself to the priest and offer what Moses commanded; the direct ritual reference is especially completed by Leviticus 14.

Jesus tells ten men with lepra/tzaraat-language to show themselves to the priests; their cleansing occurs as they go, presupposing the Levitical priestly verification/restoration system.

Numbers 12 describes Miriam being struck with a white skin condition and then shut outside the camp for seven days. That narrative lives inside the same purity world as Leviticus 13, where serious skin afflictions can require public marking and residence outside the camp. Numbers therefore gives a concrete narrative instance of exclusion without requiring a modern medical diagnosis of the condition.

Both involve outside-the-camp language, but Hebrews 13 explicitly grounds its comparison in sacrificial bodies burned outside camp, not in persons with tzaraat. A careful reading should not present Leviticus 13 as Hebrews' direct source.
