Context

This line is written by Matthew in Matthew 16:3.

Once again, the Pharisees and Sadducees are trying to get Jesus to show them a sign that he is who he says he is. Jesus must be getting pretty sick of the same ol' run-around from these guys.

And too bad for them, he won't be giving them any more signs. Those are only for evil people, apperently.

Sounds a bit fuddy-duddyish, doesn't it?
