Definitions and biblical allusions and references for first names can be found online at several sites which specialize in this information, including Behind the Name, Bible Study Tools and Baby Names. Most modern biblical name dictionaries draw from a work compiled in the 19th century by Roswell Dwight Hitchcock.
The practice of taking names from the bible invokes the character of the context of the story of the bible. When the name chosen is that of a person in the bible, the reference alludes to that person's character or situation in the biblical story. Place names can contain a more complex allusion to a setting, event or lesson given in the bible.
