Did Jonathan Cahn know that Oct 7th 2023 would happen?

Mark and Dave look at Jonathan Cahn prophecies. If Jonathan Cahn knew that Oct 7, 2023 would happen, why didn't he try to stop it?!? Is this the most evil person? What is a jubilee year in the Bible? Does God use this to mark time, give restoration, or judgment? Are we under the jubilee years?
