John 18:4 - Matthew Poole's English Annotations on the Holy Bible

This evangelist saith nothing of what the other evangelists mention, of the sign that Judas had given them, by which they should know him; nor of Judas's kissing of him, or our Saviour's reply to him. (John, all along his Gospel, mentions very little of what is recorded by the other evangelists). It must be supposed, that after Judas had kissed our Saviour, our Saviour himself came forth and asked him whom they looked for; hereby showing that he laid down his life, and no man took it from him: he could easily have delivered himself out of their hands, (though I think they are too charitable to Judas, who think that it was that which made Judas discover him; not that he designed his death), he had once and again before so escaped them; but now his hour was come, he freely offers himself unto his enemies, and asketh whom they looked for.
