Charles Ellicott Commentary Leviticus 13:5

"and the priest shall look on him the seventh day: and, behold, if in his eyes the plague be at a stay, and the plague be not spread in the skin, then the priest shall shut him up seven days more:" — Leviticus 13:5 (ASV)

And the priest shall look on him. —If at the end of a week there is no alteration in the symptoms, the case must be adjourned for another seven days. The same priest who first inspected it must examine it again, since another priest could not determine whether it has spread. If the priest died in the meantime, or became ill, another priest could examine the patient, but could not pronounce him unclean. If the seventh day happened to be a Sabbath or feast day, the case had to be postponed to the following day.

If the plague in his sight be at a stay. —Better, if the plagued spot remain the same in its colour, that is, if the suspicious spot that caused the individual to be shut up had not altered its complexion. The expression here translated “sight” is the same that is rightly rendered as “colour” in the Authorised Version in Leviticus 13:55 of this very chapter. (Compare to Numbers 11:7.) It will thus be seen that though the affected spot had not spread, still it retained its unhealthy and suspicious complexion.
