The BDB (Brown-Driver-Briggs Hebrew and English Lexicon) is a lexicon of biblical Hebrew published in 1906 by three scholars: Francis Brown took the lead, in collaboration with Samuel Rolles Driver and Charles Augustus Briggs. Based on an earlier Hebrew-German work by Wilhelm Gesenius, the BDB is a comprehensive, and comprehensively sourced, resource for studying definitions and uses of every Hebrew and Aramaic word in the Bible. It is well respected and widely used among scholars.
