John 12:10-11, 17-18

So the chief priests planned to kill Lazarus also, because on account of him many of the Jews were going away [from the teaching and traditions of the Jewish leaders] and believing in Jesus [following Him as Savior and Messiah].

So the people, who were with Him when He called Lazarus out of the tomb and raised him from the dead, continued to tell others about Him. For this reason the crowd went to meet Him, because they heard that He had performed this [miraculous] sign.
