This small Bible fits in the palm of your hand and now speaks all the books of the Bible, old and new Testament, in a real human voice. You can jump from book to book, and chapter to chapter with the press of a button. You can also jump ahead or back in 15 second intervals. It can be powered by the sun or and light source or charged from a 9 volt DC adapter (not included). Fully charged batteries will allow the unit to play for approximately 10 hours.
