Mark 14:42 (KJV)

And he cometh, and findeth them sleeping, and saith unto Peter, Simon, sleepest thou? couldest not thou watch one hour?

Watch ye and pray, lest ye enter into temptation. The spirit truly is ready, but the flesh is weak.

And again he went away, and prayed, and spake the same words.

And when he returned, he found them asleep again, (for their eyes were heavy,) neither wist they what to answer him.

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.

And immediately, while he yet spake, cometh Judas, one of the twelve, and with him a great multitude with swords and staves, from the chief priests and the scribes and the elders.

And he that betrayed him had given them a token, saying, Whomsoever I shall kiss, that same is he; take him, and lead him away safely.

And as soon as he was come, he goeth straightway to him, and saith, Master, master; and kissed him.

And they laid their hands on him, and took him.

And one of them that stood by drew a sword, and smote a servant of the high priest, and cut off his ear.
