I've made many notations to my online KJV Bible that is numerically mapped with quick access and many references. Consider using it while preparing your own Bible study as it has notes not found in any other Bible - ones that will make your studies come alive. It is a quick and easy to read online Bible even if you don't need to examine the numeric map. Every Bible chapter has a description and many verses are marked with notes that will enlighten your scripture reading.
A great Bible for your mobile browser without having to install a Bible directly on your device. Also, a mobile device eBook version is in final editing now and will be available in the next couple of weeks
