If you are looking to study the Bible properly, I recommend starting off with a good study Bible. It will provide you with comments on the text, background information to each book, cross references to other relevant Scriptures, and sidebars with information on specific topics. After that it is good to slowly build your library with the other resources mentioned below. You can get them all from Amazon.
- A Study Bible - a Bible with a running commentary from Bible scholars and book introductions that provide the background and setting of each book. Suggested: ESV Study Bible, NIV Study Bible, NASB Hebrew-Greek Key Study Bible
- A Language Dictionary - provides definitions of key words in the text. Suggested: Vine's Expository Dictionary
- A Bible Dictionary/Encyclopedia - provides background information on key words and ideas in their original setting. Suggested: Nelson's New Illustrated Bible Dictionary
- A Commentary on the Whole Bible - provides a running commentary from Bible scholars that is more comprehensive than a study Bible, but still fairly brief. Suggested: The Expositor's Bible Commentary
- Individual Book Commentaries - provides the most comprehensive commentary for each individual book of the Bible. Suggested: Tyndale New Testament Commentaries, Any commentaries by Gordon Fee, Douglas Moo, I. Howard Marshall, D. A. Carson
