'Shut' in the Bible

The priest shall examine the mark and shall quarantine the article with the mark for seven days.

then the priest shall order that they wash the thing in which the mark occurs, and he shall quarantine it for seven more days.

the priest shall go out of the house, to the doorway, and quarantine the house for seven days.

Moreover, whoever goes into the house during the time that it is quarantined becomes unclean until evening.
