Some of the Jews who witnessed this miracle reported it to the Pharisees, who called a meeting of the Sanhedrin. They began to plot Jesus’ murder. Rather than acknowledging Jesus as the Messiah because of this miracle, the chief priests also plotted to kill Lazarus to destroy the proof of Jesus’ divinity.
It reads in John 12:9-11 Easy> When the large crowd of the Jews learned that Jesus was there, they came, not only on account of him but also to see Lazarus, whom he had raised from the dead. So the chief priests made plans to put Lazarus to death as well, because on account of him many of the Jews were going away and believing in Jesus.
