“Mounce’s Complete Expository Dictionary of Old and New Testament Words” is well worth the price. It incorporates two numbering systems; the Goodrick-Kohlenberger numbering system and the Strong’s numbering system that are used throughout its three dictionaries, including an Expository Dictionary, a Hebrew-English Dictionary, and a Greek-English Dictionary. Neither numbering system is linked to the Interlinear Bibles in Logos. The Goodrick-Kohlenberger (G-K) numbering system is a newer system with up to date definitions that use the G-K number in the primary position, but it also cross-references the older Strong's number. For instance, "agapaō" is number 26 in the G-K system and number 25 in Strong's. When the G-K system does not have a Strong's equivalent, to asterisks (**) are used to indicate the exception. In addition, “Mounce’s Complete Expository Dictionary" has a Scripture Index, and other useful information, like "How to Do Word Studies".
