Mark 14:37-41 King James Version (KJV)
37 And he cometh, and findeth them sleeping, and saith unto Peter, Simon, sleepest thou? couldest not thou watch one hour?
38 Watch ye and pray, lest ye enter into temptation. The spirit truly is ready, but the flesh is weak.
39 And again he went away, and prayed, and spake the same words.
40 And when he returned, he found them asleep again, (for their eyes were heavy,) neither wist they what to answer him.
41 And he cometh the third time, and saith unto them, Sleep on now, and take your rest: it is enough, the hour is come; behold, the Son of man is betrayed into the hands of sinners.
