Mark 14:45 In-Context

43 Immediately, while he was still speaking, Judas, one of the twelve, arrived; and with him there was a crowd with swords and clubs, from the chief priests, the scribes, and the elders.
44 Now the betrayer had given them a sign, saying, "The one I will kiss is the man; arrest him and lead him away under guard."
45 So when he came, he went up to him at once and said, "Rabbi!" and kissed him.
46 Then they laid hands on him and arrested him.
47 But one of those who stood near drew his sword and struck the slave of the high priest, cutting off his ear.
