We are using the Strong's number information created by Larry Pierce, the author of the Online Bible (OLB - a Bible program for PC and Mac). Their FAQ states: “We used the Strong's system with the actual Greek and Hebrew to implement the numbers. By doing this we obtained about 15000 corrections in the Strong's concordance.”
It was Larry Pierce at the Online Bible that combined what Dr. Strong cited with Smith's Bible Dictionary and what Dr. Thayer cited in his abridged Thayer’s 1889 Greek-English Lexicon. It is keyed to the large Kittel and the “Theological Dictionary of the New Testament.” This resulted in the Greek Definitions module for the OLB. Online Bible also altered Thayer’s definitions concerning the Holy Spirit and the divinity of Christ since Thayer was a Unitarian. Larry and the developers of OLB did the same with the Old Testament in that they combined Dr. Strong’s citings with Brown, Driver, and Briggs’ work on the Gesenius Lexicon; this is keyed to the “Theological Word Book of the Old Testament.”
Originally, the Greek text of the New Testament according to the Nestle-Aland 26th edition/UBS 3rd edition (N26) as included as part of the Online Bible software program, and the Biblia Hebraica Stuttgartensia text (BHS) of the Hebrew Old Testament were extensively adapted, altered, proofed, and corrected by Maurice A. Robinson and Larry Pierce from texts conforming to that distributed by the External Services Division of the Center for Computer Analysis of Texts (CCAT) of the University of Pennsylvania.
BLB obtained permission for the Lexicon information from Larry Pierce early in its inception. Subsequently, we have added facsimile images of both Thayer’s and Gesenius’ Lexicons to our language tools.
Larry Pierce has published “Tense Voice Mood” which is a database of parsings for every verb in Biblia Hebraica Stuttgartensia Hebrew and Nestle-Aland, Byzantine Majority, and Textus Receptus 1550 Greek texts. Verbs’ forms are assigned numbers like Strong’s numbers. The parsings are based on two 19th century works edited by George V. Wigram: Analytical Greek Lexicon of the New Testament and Englishman’s Hebrew and Chaldee Concordance of the Old Testament.
We have subsequently added Strong's definitions to both our Hebrew and Greek Lexicon pages.
