43 Immediately, while he was still speaking, Judas, one of the twelve, came—and with him a multitude with swords and clubs, from the chief priests, the scribes, and the elders. 44 Now he who betrayed him had given them a sign, saying, “Whoever I will kiss, that is he. Seize him, and lead him away safely.” 45 When he had come, immediately he came to him, and said, “Rabbi! Rabbi!” and kissed him. 46 They laid their hands on him, and seized him.

Commentary on Mark 14:43-52
(Read Mark 14:43-52)
Because Christ appeared not as a temporal prince, but preached repentance, reformation, and a holy life, and directed men's thoughts, and affections, and aims to another world, therefore the Jewish rulers sought to destroy him. Peter wounded one of the band. It is easier to fight for Christ than to die for him. But there is a great difference between faulty disciples and hypocrites. The latter rashly and without thought call Christ Master, and express great affection for him, yet betray him to his enemies. Thus they hasten their own destruction.
