Leviticus 13:5-7

Expanded Bible

⁵ On the seventh day the priest must ·look at [examine] the person again. If he sees that the sore has not changed and it has not spread on the skin, the priest must keep the person ·separated [confined; quarantined] for seven more days. ⁶ On the seventh day the priest must ·look at [examine] the person again. If the sore has faded and has not spread on the skin, the priest must announce that the person is clean [^Cin a ritual sense]. The sore is only a ·rash [eruption]. The person must wash his clothes, and he will become clean again.

⁷ “But if the ·rash [eruption] spreads again after the priest has announced him clean [^Cin a ritual sense], the person must come again to the priest.
