But Peter followed Him from a distance [as they were going] to the courtyard of the head priest. He went inside [i.e., eventually. See John 18:15-16] and sat down with the [Jewish] officers to see how things would turn out [i.e., with Jesus’ trial].
So, the leading priests and the Pharisees assembled the Council [Note: This was the Jewish governing body called “the Sanhedrin”] and said, “What should we do, for this man is performing many [miraculous] signs?
The Pharisees [i.e., a strict sect of the Jewish religion] heard the crowd whispering these things about Him, so the leading priests and Pharisees sent some Temple guards to arrest Him.
His parents said these things because they were afraid of the Jewish authorities who had already decided that anyone who confessed Jesus to be the Christ would be expelled from the synagogue.
