Then certain philosophers of the Epicureans, and of the Stoicks, encountered him. And some said, What will this babbler say? other some, He seemeth to be a setter forth of strange gods: because he preached unto them Jesus, and the resurrection.

A wise man will hold his tongue till he see opportunity: but a babbler and a fool will regard no time.
