Bible Study Tools #4: Lexicons & Dictionaries
Lexicons & dictionaries can reveal what might be “lost in translation” but they also tempt us to fall into the trap of “I learned a fact about a word and I must use it.”
Bible Study Tools #3: Concordances
A concordance is an organized list of all the biblical texts which contain a given word. Concordances allow you to broaden your understanding of how a word is used and its range of meanings.
