And suddenly, when they had looked round about, they saw no man any more, save Jesus only with themselves.

Lest coming suddenly he find you sleeping.

While He was still speaking, Judas, one of the Twelve, suddenly arrived. With him was a mob, with swords and clubs, from the chief priests, the scribes, and the elders.
