And the priest shall look on him the seventh day
In the day, and not in the night, as Maimonides, but not on the seventh day, if it happened to be on the sabbath F6, then it was put off till after it; and, according to the Jewish canons F7, they do not look upon plagues in the morning, nor in the evening, nor in the middle of a house, nor on a cloudy day, nor at noon, but at the fourth, fifth, eighth, and ninth hours:
and, behold, [if] the plague in his sight be at a stay;
it appears to the priest, according to the strictest view he can take of it, that it is in the same state and condition it was, neither better nor worse:
[and] the plague spread not in the skin:
is not greater or larger than it was, though not less:
then the priest shall shut him up seven days more;
such abundant care was taken, lest after all it should prove a leprosy.
