Some have asked what version to memorize. My answer is, memorize from the version you like the best. When you memorize, you say passages of scripture over to yourself many times. You will want to enjoy and appreciate the language of the text you are using. Hundreds of Grace Notes subscribers are memorizing the Bible books that they study, in many different languages, so you are the best judge of what type of Bible to use.
Some newer versions seem to be more clear in many places, and sometimes more accurate.
So make the choice that you can stay with. Others will type each chapter on a piece of paper and carry it in a legal folder. Some have pocket Testaments. You'll gravitate into a system that works for you. There are many methods for memorization.
