We just learned that Jesus had gone off to a place called Gethsemene and prayed to God about the job he knew he had to do.
When he was there with his apostles, Judas came up to Jesus and gave him a kiss.
There were guards with Judas, hired by people that did not like Jesus.
When Judas gave Jesus a kiss, that was to tell the guards who Jesus was, and they came and arrested him.
(from: wikipedia - kiss of judas)
Jesus knew that Judas would betray him, as he had told him at the Last Supper.
