Last April 7, my wife bought me an ESV Study Bible. I am now using it for my daily Bible reading. I recommend it to those who want to dig deeper for the treasures of the Word of God.
The ESV Study Bible was created to help people understand the Bible in a deeper way—that is, to encounter the timeless truth of God’s Word as a powerful, compelling, life-changing reality. To accomplish this purpose, the ESV Study Bible combines the best and most recent evangelical scholarship with the ESV Bible text, which, as an “essentially literal” translation, is especially suited for Bible study. The result is the most comprehensive study Bible ever published—with completely new notes, maps, illustrations, charts, timelines, articles, and other features. Created by an exceptional team of 95 evangelical Christian scholars and teachers, the ESV Study Bible contains more than 2 million words of Bible text and insightful explanation and teaching—equivalent to a 20-volume Bible resource library.
