If you have a translation other than NIV, use one of the other concordances, such as Strong's Exhaustive Concordance (REF 220.2 St8s). There are several others on the shelf, all of which use the Strong's numerical system. Be careful to look on the cover or inside the book to identify the book using the correct translation.
Sometimes students have to look up the word in the Theological Wordbook of the Old Testament (TWOT; REF 221.44 T342 1980). This book has its own numbering system, distinct from Strong's or GK. You can find a conversion chart for Strong's to TWOT in the back of the book.
Accessing the TDOT
Accessing the articles in the Theological Dictionary of the Old Testament (TDOT) is tricky if you don't know Hebrew. However, there are a few ways you can use to access this resource. Note that the TDOT does not contain every Hebrew word in the Old Testament, rather it only has a selection of theologically important words.
