In the book Numbers,as well as Exodus and Leviticus,I think. There seems to be frequent mention of one being "shut out" mostly when one has sined, or unclean EXAMPLE:Num. 12:14 something of the sort. ANYWAY I just don't understand what it means by let them be "shut out seven days " what happens during the time? Like what is it that these people did during that time that God would say "he is clean"or "be received in again" stuff like that like what is the shut out thing all about!!!?
