WHAT IS IT, EXACTLY?
The purpose of the Concise Bible Notes series is to provide the student of God’s word with some simple and concise supplemental material to foster biblical study. These notes are not intended to bog down the student but simply to offer some short, practical explanations to help the reader through the Bible. You can think of these concise notes as simply footnotes that are included in the text of Scripture (shown in brackets [concise notes found here]) that will offer the reader some additional explanation of the text.
