Why did Jesus fold the napkin?

Why did Jesus fold the linen burial cloth after His resurrection? I never 
noticed this.... The Gospel of John (20:7) tells us that the napkin, which was 
placed over the face of Jesus, was not just thrown aside like the grave clothes. 
The Bible takes an entire verse to tell us that the napkin was neatly folded, 
and was placed at the head of that stony coffin.

'Early Sunday morning, while it was still dark, Mary Magdalene came to the 

tomb and found that the stone had been rolled away from the entrance. She ran 
and found Simon Peter and the other disciple, the one whom Jesus loved. She 
said, 'They have taken the Lord's body out of the tomb, and I don't know where 
they have put him!'

Peter and the other disciple ran to the tomb to see. The other disciple out ran 
Peter and got there first. He stopped and looked in and saw the linen cloth 
lying there, but he didn't go in. Then Simon Peter arrived and went inside. He 
also noticed the linen wrappings lying there, while the cloth that had covered 
Jesus' head was folded up and lying to the side.'

Was that important? Absolutely! Is it really significant? Yes!
In order to understand the significance of the folded napkin, you have to 
understand a little bit about Hebrew tradition of that day.
The folded napkin had to do with the Master and Servant, and every Jewish boy 
knew this tradition. When the servant set the dinner table for the master, he 
made sure that it was exactly the way the master wanted it. The table was 
furnished perfectly, and then the servant would wait, just out of sight, until 
the master had finished eating, and the servant would not dare touch that table, 
until the master was finished.

Now if the master were done eating, he would rise from the table, wipe his 
fingers, his mouth, and clean his beard, and would wad up that napkin and toss 
it onto the table. The servant would then know to clear the table. For in those days, the wadded 
napkin meant,  "I'm finished." But if the master got up from the table, and folded his napkin, and laid it 
beside his plate, the servant would not dare touch the table, because..........

The folded napkin meant, "I'm coming back!"
