Leviticus 13:34

And in the seventh day the priest shall look on the scall: and, behold, if the scall be not spread in the skin, nor be in sight deeper than the skin; then the priest shall pronounce him clean: and he shall wash his clothes, and be clean.

Cross-references

Leviticus 13:6 also describes a seventh-day examination with similar outcome—identical procedure for a different condition.

Leviticus 13:23 applies the same non-spreading criterion for a boil scar—reinforcing the diagnostic principle.

Leviticus 13:30 describes a case leading to uncleanness—contrasts with the clean verdict here. Both involve priestly examination.
