'Mockers' in the Bible

"Look, you mockers! Be amazed and die! Since I am performing an action in your days, one that you would not believe even if someone told you!'"

First of all you must understand this: In the last days mockers will come and, following their own desires, will ridicule us

How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.
