The Jewish leaders decided to kill Lazarus, too.

John 12:9-11

9 A large crowd of Jews heard people say that Jesus was there in Bethany. So they came, not only to see Jesus but also to see Lazarus, the man whom he had caused to become alive again after he died. 10 So the chief priests decided to kill Lazarus also, 11 because many of the Jews were deserting them and going to Jesus and believing in him because of Jesus causing Lazarus to be alive again.
