"Jesus answered nothing to the many questions put to Him by Herod; neither did He reply to His enemies, who were vehemently accusing Him. Herod was enraged because Jesus did not appear to fear his power, and with his men of war he derided, mocked, and abused the Son of God. Yet he was astonished at the noble, Godlike appearance of Jesus when shamefully abused, and fearing to condemn Him, he sent Him again to Pilate. EW 174.1"
"Then he questioned with him in many words; but he answered him nothing."
The EGW passage directly echoes Luke 23:9, stating that Jesus answered Herod nothing. The context and details are expanded upon, but the core event is the same.
"He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth."
Both passages describe Jesus' silence in the face of accusations and suffering. While Luke 23:9 focuses on his silence before Herod, and Isaiah 53:7 speaks of his general silence during his affliction, the EGW passage connects both ideas, highlighting Jesus' refusal to defend himself. This is more than a vague thematic overlap; it's a specific application of the Isaiah prophecy in the context of Jesus' trial before Herod.
"And notwithstanding he placed the blood of Jesus upon His accusers, and the multitude received it, crying, “His blood be on us, and on our children,” yet Pilate was not clear; he was guilty of the blood of Christ. For his own selfish interest, his love of honor from the great men of earth, he delivered an innocent man to die. If Pilate had followed his own convictions, he would have had nothing to do with condemning Jesus. EW 174.2"
"Then answered all the people, and said, His blood be on us, and on our children."
EGW directly quotes and references the verse about the people's declaration regarding Jesus' blood.
"The appearance and words of Jesus during His trial made a deep impression upon the minds of many who were present on that occasion. The result of the influence thus exerted was apparent after His resurrection. Among those who were then added to the church, there were many whose conviction dated from the time of Jesus’ trial. EW 174.3"
"Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls."
The EGW passage suggests that Jesus' trial influenced people who later joined the church. Acts 2:41 describes a large number of people being added to the church after hearing Peter's sermon. While not a direct cause-and-effect, there is a thematic parallel between the impact of Jesus' ministry and the growth of the early church.
