And he cometh the third time
 After he had prayed a third time, to the same purport as before: 
 and saith unto them, sleep on now, and take your rest;
 which words are spoken ironically: 
 it is enough;
 or "the end is come"; as the Syriac and Arabic versions render it, of watching and praying: 
 the hour is come, behold the son of man is betrayed into the hands
 of sinners;
 both Jews and Gentiles, by one of his own disciples; (See Gill on Matthew 26:45).
