Luke 22:44-48

And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground.

And when he rose up from prayer, and was come to his disciples, he found them sleeping for sorrow,

And said unto them, Why sleep ye? rise and pray, lest ye enter into temptation.

And while he yet spake, behold a multitude, and he that was called Judas, one of the twelve, went before them, and drew near unto Jesus to kiss him.

But Jesus said unto him, Judas, betrayest thou the Son of man with a kiss?
