Concordance: A concordance is an alphabetical listing of words used in the Bible along with the verses where those words can be found throughout the Bible. To give you some context, the list of verses usually includes part of the sentence where the word is used.
Many Bibles have a condensed concordance at the back of the Bible. However, for study purposes it may be helpful for you to purchase an “exhaustive concordance,” where you will find every word of the Bible listed and every reference in which that word is found. Exhaustive concordances are published by the same companies that publish the Bibles. Each concordance corresponds to the English translation of the Bible published by that company (such as NASB or NIV).
A good concordance will have in its main section all the English words used in the Bible. It will also have a corresponding Greek and Hebrew section where you will find the original language word, its various meanings and how it was used in the original writing. There will be a numbering system for ease in finding these original language words. Whenever one language is translated into another, some of the original meaning can be lost. Looking at the original language words will enhance your understanding of Scripture.
Look up the word plans in the concordance at the back of your Bible and in an exhaustive concordance. Are the same verses listed in both places?
Read two or three of the verses in their Bible location. Read a few verses before and after your chosen verses to understand the context in which the word plans is found. What do you think each author was trying to say by using the word plans? (Notice some uses are positive and some are negative.)
In the exhaustive concordance notice the number code before or after the reference. Find this number in the language dictionary at the back of the concordance. You will find the original language word and its full meaning. How does this meaning enhance your understanding of the verses in which you find the word plans?
Dictionaries: It is always helpful to have a good English dictionary at hand when you are studying the Bible. When you come across a word you are not familiar with, look it up in the dictionary. Or when you want to know the full meaning of a word and how it fits in a particular passage, look it up in the dictionary for all the meanings of that word.
