Matthew 26:14-16, 47-50

Then Judas Iscariot, one of the twelve disciples, went to the leading priests and asked, “How much will you pay me to betray Jesus to you?” And they gave him thirty pieces of silver. From that time on, Judas began looking for an opportunity to betray Jesus.

And even as Jesus said this, Judas, one of the twelve disciples, arrived with a crowd of men armed with swords and clubs. They had been sent by the leading priests and elders of the people. The traitor, Judas, had given them a prearranged signal: “You will know which one to arrest when I greet him with a kiss.” So Judas came straight to Jesus. “Greetings, Rabbi!” he exclaimed and gave him the kiss. Jesus said, “My friend, go ahead and do what you have come for.” Then the others grabbed Jesus and arrested him.
