And he cometh and findeth them sleeping
 His three disciples, Peter, James, and John: 
 and saith unto Peter;
 particularly, he having so lately asserted, with so much confidence, his love to Christ, and close attachment to him: 
 Simon, sleepest thou?
 Christ calls him by the name he first went by, and not by that which he had given him, Cephas, or Peter; he not now having that firmness and constancy, though he boasted of it, which answers to that name: 
 couldst thou not watch one hour?
 The Arabic and Persic versions add, with me; and so does the Complutensian edition; (See Gill on Matthew 26:40).
