"This body was made up of members chosen from the priesthood, and from the chief rulers and teachers of the nation. The high priest was usually the president. All its members were to be men advanced in years, though not aged; men of learning, not only versed in Jewish religion and history, but in general knowledge. They were to be without physical blemish, and must be married men, and fathers, as being more likely than others to be humane and considerate. Their place of meeting was an apartment connected with the temple at Jerusalem. In the days of Jewish independence the Sanhedrin was the supreme court of the nation, possessing secular as well as ecclesiastical authority. Though now subordinated by the Roman governors, it still exercised a strong influence in civil as well as religious matters. DA 133.1"
"Then assembled together the chief priests, and the scribes, and the elders of the people, unto the palace of the high priest, who was called Caiaphas,"
The EGW passage provides a detailed description of the Sanhedrin, its composition, qualifications of its members, and its role in Jewish society. Matthew 26:3 mentions the assembly of the chief priests, scribes, and elders, which is a reference to the Sanhedrin. The EGW passage expands upon the biblical reference, providing more information about the institution.
"The Sanhedrin could not well defer an investigation of John's work. There were some who recalled the revelation made to Zacharias in the temple, and the father's prophecy, that had pointed to his child as the Messiah's herald. In the tumults and changes of thirty years, these things had in a great measure been lost sight of. They were now called to mind by the excitement concerning the ministry of John. DA 133.2"
"There was in the days of Herod, the king of Judea, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth. And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless. And they had no child, because that Elisabeth was barren, and they both were now well stricken in years. And it came to pass, that while he executed the priest’s office before God in the order of his course, According to the custom of the priest’s office, his lot was to burn incense when he went into the temple of the Lord. And the whole multitude of the people were praying without at the time of incense. And there appeared unto him an angel of the Lord standing on the right side of the altar of incense. And when Zacharias saw him, he was troubled, and fear fell upon him. But the angel said unto him, Fear not, Zacharias: for thy prayer is heard; and thy wife Elisabeth shall bear thee a son, and thou shalt call his name John. And thou shalt have joy and gladness; and many shall rejoice at his birth. For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and he shall be filled with the Holy Ghost, even from his mother’s womb. And many of the children of Israel shall he turn to the Lord their God. And he shall go before him in the spirit and power of Elias, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord. And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years. And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and am sent to speak unto thee, and to shew thee these glad tidings. And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season. And the people waited for Zacharias, and marvelled that he tarried so long in the temple. And when he came out, he could not speak unto them: and they perceived that he had seen a vision in the temple: for he beckoned unto them, and remained speechless. And it came to pass, that, as soon as the days of his ministration were accomplished, he departed to his own house. And after those days his wife Elisabeth conceived, and hid herself five months, saying,"
The EGW passage directly references the events surrounding Zacharias and the prophecy concerning John, as described in Luke 1:5-25. It highlights the Sanhedrin's awareness of these past events and their relevance to John's ministry.
"either to sanction or to reject John's work. Already their power over the people was waning. It was becoming a serious question how to maintain their position. In the hope of arriving at some conclusion, they dispatched to the Jordan a deputation of priests and Levites to confer with the new teacher. DA 133.3"
"And this is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him, Who art thou?"
The EGW passage directly refers to the sending of priests and Levites to question John, which is the central event described in John 1:19.
"A multitude were gathered, listening to his words, when the delegates approached. With an air of authority designed to impress the people and to command the deference of the prophet the haughty rabbis came. With a movement of respect, almost of fear, the crowd opened to let them pass. The great men, in their rich robes, in the pride of rank and power, stood before the prophet of the wilderness. DA 133.4"
"But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come?"
Both passages describe a confrontation between religious leaders (Pharisees/Sadducees and Rabbis) and a prophet (John the Baptist and Jesus, respectively). Both involve a sense of authority and a reaction from the crowd. The EGW passage amplifies the scene described in Matthew.
