Then one of the twelve, called Judas Iscariot, went unto the chief priests,

When the even was come, he sat down with the twelve.

While he yet spake, Lo, Judas, one of the twelve, came: and with him a great multitude with swords and staves, which were sent from the chief priests and elders of the people.
