" As we see from the Scriptures, it had become a common and proverbial expression that if someone wanted to refer to a prophet, he called him a “fool.” So in the history of Jehu (2 Kings 9:11), they said of a prophet: “Why did this mad fellow come to you?” And Isaiah shows (Is. 57:4) that they opened their mouths and put out their tongues against him. But all they accomplished by this was to become a terrible stench and a curse, while the dear prophets and saints have honor, praise, and acclaim throughout the world and are ruling forever with Christ, the Lord. "
