Proofread or perish
A proofreading error in 1631 could have changed the Bible’s Ten Commandments as we know it and highlights the importance of not leaving anything to chance when you’re about to sign off on any important piece of communication.
In 1631, a printer in London printed and distributed 1,000 copies of the bible. All was well until people started to discover that there was a mistake in the Ten Commandments. The word not had been left out of the seventh commandment and worshipers were subsequently instructed to commit adultery. King Charles I fined the printers and demanded all 1000 copies were burned but unfortunately seven copies did survive and the mistake remains for all to see.
Proofreading is just as essential to exacting your communications as the preceding editing processes such as the structure, language and copy editing which focus on diction, spelling, grammar, punctuation and stylistic errors (see levels of editing
here).
When you have to convince a client, an employer or the public of your professionalism, you don’t want to be dismissed as second-rate or have the message you’re trying to communicate misrepresented by a mistake that could easily have been avoided if the document was given a thorough proofreading.
