Caiaphas then condemned Jesus to death. In Mark 14:63-64, we read: “Then the high priest tore his clothes and said, “What further need do we have of witnesses? You have heard the blasphemy! What do you think?” And they all condemned Him to be worthy of death.”
Caiaphas then had to persuade the Romans to execute Jesus. Israel was an occupied territory, and the Jews did not have the authority to execute prisoners.
