I have many different study bibles that I've used over the years. My two favorites are the A.W. Tozer (KJV) bible because I love the way he put things, and my daily and church bible... my Ryrie (KJV) bible. I do have a Reese (KJV) chronological study bible that is alright. I also use a Scofield (KJV) study bible from time to time. But I have to admit...my go to study tool is a program you can download to your pc called E-Sword. It has so many different tools inside the program (for free) such as concordances, dictionaries, commentaries, etc, etc.
