What is "brown-driver-briggs"

A Hebrew and English Lexicon of the Old Testament, more commonly known as Brown–Driver–Briggs or BDB (from the name of its three authors) is a standard reference for Biblical Hebrew and Aramaic, first published in 1906. It is organized by (Hebrew) alphabetical order of three letter roots. It was based on the Hebrew-German lexicon of Wilhelm Gesenius, translated by Edward Robinson. The chief editor was Francis Brown, with the co-operation of Samuel Rolles Driver and Charles Augustus Briggs, hence the name Brown–Driver–Briggs. Some modern printings have added the Strong's reference numbers for Biblical Hebrew and Aramaic words.

Renowned semitists Jo Ann Hackett and John Huehnergard are currently in the process of creating a revision of BDB that incorporates contemporary scholarship.
