A servant is not permitted to talk back; he or she must submit to the will of the master or mistress. Jesus Christ was silent before those who accused Him as well as those who afflicted Him. He was silent before Caiaphas (Matt. 26:62–63), the chief priests and elders (27:12), Pilate (27:14; John 19:9) and Herod Antipas (Luke 23:9). He did not speak when the soldiers mocked Him and beat Him (1 Peter 2:21–23). This is what impressed the Ethiopian treasurer as he read this passage in Isaiah (Acts 8:26–40).
Isaiah 53:7 speaks of His silence under suffering and verse 8 of His silence when illegally tried and condemned to death. In today’s courts, a person can be found guilty of terrible crimes; but if it can be proved that something in the trial was illegal, the case must be tried again. Everything about His trials was illegal, yet Jesus did not appeal for another trial. “The cup which My Father hath given Me, shall I not drink it?” (John 18:11)
