Sometimes we read scripture and breeze past somne very significant things, simply because we lack the historical context. Let me start with a smal part of the resurrection narrative.. (John 20:6,7).
" Then cometh Simoin Peter following him, and went into the sepelchre, and seeth the linen clothes lie. And the napkin, that was about his head, not lying with the linen clothes, but wrapped together in a place by itself."
In ancient Israel as the master (of the house) gathered with his family at table, it was avery important time. A time of sharing with each member of the family. If the master stood to leave the table for any reason, his table napkin was a signal to his servants.
If he crumpled the napkin carelessly and dropped it on the table, that was a signal which said, " I'm all done here, you can clean this stuff away..I am leaving this table and not coming back".
On the other hand, if the master carefully folds the napkin and places it neatly upon the table he is saying, " Don't change a thing, don't take things away, please family, continue on here...because I am COMING BACK " !!!
