A couple of days ago I ran into some biblical text and I can not get it out of my mind. After the last supper Jesus went with Peter the fisherman and the two sons of Zebedee in a place called Getshemane to pray (see more details in Mt 26:36-38). Before going farther to pray He asked the disciples to "Stay here and keep watch with me". The King James version is a bit different though, but the message is the same. The disciples were supposed to watch over Him during the prayer to the Father.
The question raised here is: Why was so important to watch over Him? He knew that Judas will kiss him and trade him for 30 pieces of silver. Why was He afraid of? Why was necessary to watch over Him?
