What does John 18:12-14 mean?

12 Then the band and the captain and officers of the Jews took Jesus, and bound him, 13 And led him away to Annas first; for he was father in law to Caiaphas, which was the high priest that same year. 14 Now Caiaphas was he, which gave counsel to the Jews, that it was expedient that one man should die for the people. (John 18:12-14 KJV)

William Burkitt’s Commentary

Judas having made good his promise to the chief priests, and delivered Jesus a prisoner bound into their hands, those evening wolves no sooner seize the Lamb of God, but they thirst and long to suck his innocent blood; yet, lest it should look like a downright murder, they allow him a mock-trial, and abuse the law by perverting it to injustice and bloodshed. How impossible is it for the greatest innocence and virtue to protect from slander and false accusation! and no person can be so innocent or good, whom false witnesses may not condemn.
