Was not Micah prophesying long after Jezebel was already dead?

So who was this woman spoken about in Micah 7, that was also trodden down?

Micah 7:10 Then she that is mine enemy shall see it, and shame shall cover her which said unto me, Where is the LORD thy God? mine eyes shall behold her: now shall she be trodden down as the mire of the streets.
