“But the chief priests consulted that they might put Lazarus also to death;”
King James Version (KJV)
12:10 The chief priests consulted, how to kill Lazarus also - Here is the plain reason why the other evangelists, who wrote while Lazarus was living, did not relate his story.
Joh 12:10,11 The chief priests consulted. Lazarus was a living proof of the Divine power of Christ, and they wished him out of the way.
