From the experts:
For the seriously audacious biblical baby namer who wants to move beyond Elijah and Josiah, this name has considerable old-fangled charm. Obadiah, who gave his name to one of the shortest books in the Bible, was a rich man who had the gift of prophecy. There are several other men named Obadiah in the Bible, as well as a Saint Obadiah. There have been two prominent U.S. senators named Obadiah.
In literature, there is an Obadiah in Laurence Sterne's novel Tristan Shandy, one in Tobias Smollett's The Expedition of Humphry Clinker, and another in Anthony Trollope's Barchester Towers--as well as a villain in the Iron Man series.
