The Holy Bible: Easy to Read understand Version (ERV) is an English translation of the Bible compiled by the World Bible Translation Center. It was originally published as the English Version for the Deaf (EVD) by BakerBooks. Deaf readers sometimes struggle with reading English because sign language is their first language. The World Bible Translation Center (WBTC) decided to do a translation that would make reading the Bible easier for them. The EVD uses simpler vocabulary and shorter sentences to make it simpler to understand. Ervin Bishop did most of the translating for the WBTC. He used a thought-for-thought or functional equivalence method of translation. It was found to be useful for others who struggle with reading and is often used in prisons and literacy programs.
